10th Street Bridge

Posted on by

The 10th Street Bridge (which a reader pointed out is nicknamed the Phillip Murray Bridge after the first president of the United Steelworkers of America) was the last of the bridges over the Monongahela River for me to walk.  Or so I thought.  It turns out that the Liberty Bridge also has a sidewalk despite the fact that it is a freeway bridge like the Veteran’s Bridge (see post).  So I’ll have to come back to the Liberty Bridge at some point.

I delayed my walk of the 10th Street Bridge in part because it seemed like an awkward one to get to and from.  One end is in the middle of the South Side, but the other connects to the Armstrong Tunnel, which would obviously not be pedestrian friendly.  Last week, I finally went out and walked it and as I hoped, it turns out there is a pedestrian access over the hill to the high-bus-traffic corridor of Fifth and Forbes avenues in the form of a giant staircase that I will address in another post.  This end of the 10th Street Bridge was more well-connected than I had anticipated.  Not only do the stairs provide access to the top of the hill when Duquesne University sits, but there is also access to a parking lot down by the river which also connects to the Three Rivers Trail System.  The best proof of this bridge’s connectivity is the number of other pedestrians I saw walking the bridge.  While I did not keep a count, I noticed that there was a comparatively high level of pedestrian traffic.  It certainly wasn’t as much as the Smithfield Street Bridge (see post), but it was comparable to or higher than that on the other downtown bridges.

My favorite part about this bridge was the dinosaurs painted at the top of the southern tower.  I couldn’t tell if they were official or freelance graffiti, but it seemed appropriate given that Pittsburgh is famous for dinosaurs.  Andrew Carnegie brought the first dinosaur skeletons on display anywhere in the world to his natural history museum.  I found someone else wrote a post about the dinosaurs on the bridge, which the artist apparently calls geese, which suggests that the painting may not have been officially sanctioned.

The post mentioned above about the dinosaurs also comments on the “rusty” condition of the bridge.  While I didn’t notice the rust much (it wasn’t nearly as bad as the 28th Street Bridge), I did notice the condition of the sidewalk.  I thought my theory that the top of the sidewalk had worn away to expose the metal framework supporting the structure rather farfetched, as how could the entire sidewalk (on both sides as far as I could tell) wear out so evenly.  Yet, I cannot think of any other sidewalk I’ve walked that looks like this and given the other bloggers comments on the poor physical condition of the bridge, perhaps my idea isn’t totally crazy?

Pedestrian Bridges: Bigelow Blvd

Posted on by

There is a pedestrian bridge across Bigelow Boulevard at the Bloomfield Bridge.  I walked this bridge before I started this blog and didn’t think to take a picture of the bridge itself.  Its appearance is similar to the Graham Street Pedestrian Bridge (see post) except that the fencing doesn’t connect overhead and does continue along the stairs.

The picture above is from the Bigelow pedestrian bridge looking out over Pittsburgh’s East End.  The large brownish building on the left is West Penn Hospital in Bloomfield.  In the middle of the frame are two white points standing above the other buildings.  These are the steeple of East Liberty Presbyterian Church on the left and the Highland Building, also in East Liberty and designed by Daniel Burnham, on the right.

When I saw this symbol on the pedestrian bridge, I stopped to consider it.  This was the first time I had ever seen this symbol.  I thought whoever put it on this bridge had a very good point.  The only way to access the Bloomfield Bridge from Oakland and the uphill side of Bigelow Boulevard is by the pedestrian bridge, which is only accessible by a set of stairs on either side.  As such anyone with a mobility disability is barred from using the Bloomfield Bridge as a pedestrian.  The way the intersection of the bridge and the boulevard is set up now, it would not be safe for any pedestrian to attempt to cross the streets, let alone one with a disability.  This is a unequal and limiting situation.  There is a grocery store across from the other end of the bridge and a drug store and restaurants within another block.  Up the hill from this side of the bridge is a residential area.  The other end of the Bloomfield Bridge is the residents closest area for essentials found at grocery and drug stores as well as entertainment found at restaurants and bars.  It would be highly convenient for the residents on the hill to be able to walk to this area; however the current situation limits who is able to use this resource.  (Not to mention the ugliness of the bridge and the intersection which probably discourages many people from even considering the short walk across the Bloomfield Bridge.)

The second time I saw this graffiti symbol was on the 16th Street Bridge (see post).  I could not figure out what statement, if any, the 16th Street Bridge one was trying to communicate.  As far as I could tell, that bridge is accessible to any pedestrian with or without mobility issues.  At least there are no stairs to contend with at either end.

Pedestrian Bridges: Bates Street

Posted on by

The trail bridge over Bates Street, which opened in 2011, is the second newest bridge in Pittsburgh.  The newest is the pedestrian bridge in East Liberty (see Taking the Long Way Round post).  The East Liberty bridge was a completely new bridge, whereas there was a trail bridge over Bates Street before.  This bridge carries the Eliza Furnace Trail.  This trail is part of the larger Three Rivers Heritage Trail.  I believe that this is the only bridge over a road along the Three Rivers Trail system.  There is a converted railroad bridge that carries the trial over part of the Allegheny River (see July 15 post).  The Hot Metal (Aug 9 post), Smithfield Street and Fort Duquesne (June 19 post) bridges are also considered part of the trail system according to the trail map.

As I mentioned in the Birmingham Bridge post, the part of the Three Rivers Trail system that travels on the northern side of the Monongahela is not a very pleasant stretch.  This area around the Bates Street Bridge is one of the worst sections.  The trail is caught between a freeway and the high traffic, through way of Second Avenue.  There is no vegetation or anything else to act as barriers to the noise of the traffic on these two roads and to the sun on a hot day.

Further away from town (in the direction the picture above looks), the trail improves some as it comes to an elevation between that of the freeway and Second Avenue and there is more space between the trail and the roads.  I’ve traveled on this trail toward town only once or twice, so I don’t remember specifics about it.  I do remember that it does continue to lean toward being unpleasant.  The times I traveled on it, I was biking.  From that experience I know I would never choose to walk it.  On a bike, you go fast enough to ignore much of the harshness of the trail, but walking you would be forced to take it all in.

Perhaps the biggest problem with this part of the trail system is that it doesn’t approach anywhere near the river.  This is a significant flaw for a trail considered part of a river trail system.  At the Bates Street Bridge, the trail is separated from the Monongahela River by Second Avenue and the office/technology park I reference in the Birmingham Bridge post.

One of my original fascinations with my walking bridge project was the different views of the city captured from the various bridges.  The Bates Street Bridge adds to the views of downtown I’ve collected so far:

Hot Metal Bridge

Posted on by

After walking the Hot Metal Bridge, I realized that it is really three separate bridges.  One of the bridges is the bike/pedestrian bridge pictured above that crosses over Second Avenue.  The other two are in the background of the image above–one carries all vehicular traffic while the other carries all pedestrians and bicycles.  The bridge pictured above is not structurally connected with either of the other bridges.  The two bridges that span the Monongahela River were built at different times.  While at this end (north) the bridges are at the same level, they are at two different elevations on the other side of the river.

The Hot Metal Bridge is one of the more locally famous and popular bridges in the city.  In my experience of participating in and overhearing people’s conversations locally about Pittsburgh bridges, the Hot Metal and Smithfield Street bridges are the two that come up the most as fun to use and interesting.  In the case of the Hot Metal Bridge, this is perhaps because it used to be a set of railroad bridges which have now been converted.  They were built and used by the Jones & Laughlin Company to connect its sites on opposites of the river.  The name of the bridge (Hot Metal) came from the fact that the trains were carrying molten metal from one factory to another.  There are, or at least there were, placards along Water Street along the South Side Works that describe the history of the J&L steel company on this site and on the bridge.  I don’t know if they are still up as there is currently construction going on in this area.

According to the description attached to the oldest image of the bridge on Historic Pittsburgh, the bridge was built in 1887.  This image, as well as PGHbridges.com’s page for the bridge, identifies the names of the two structures as the Monongahela Connecting Railroad Bridge (now the vehicular bridge) and the Hot Metal Bridge (now the pedestrian bridge).  The G.M. Hopkins maps tell a slightly different story.  As early as 1882, the maps show a bridge at this location.  That map and the 1889 map identify the bridge as the East End Bridge.  All the maps from 1890 through 1923 of this site call it the Jones & Laughlins Bridge.  Up until 1904, the bridge is depicted as carrying a single track, which I assume would be the bridge that is now the pedestrian bridge.  Starting in 1910, the bridge is depicted with three railroad tracks, meaning the current vehicular bridge was added in that time.

It is amazing to me that as late as 1998 this part of the city was still dominated by steel mill buildings as illustrated by this photo.  I suppose this means that I did not come to this part of the city then.  As the South Side Works mall did not exist yet, I guess there was no reason for me to come over here.  According to PGHbridges.com, the conversion of the bridges began in 1998, but the larger of the two bridges didn’t open until 2000 while the pedestrian bridge opened in 2007.

My final comment on this bridge is that there is a nice view of downtown from here, although the buildings don’t form any interesting patterns and clusters like they did in the views from the Allegheny River bridges (see 16th Street Bridge post for an example of this).

Pedestrian Bridges: Shadyside

Posted on by

When the pedestrian bridge I discuss in “Taking the Long Way Round” was in the process of being built, I was thinking it was the first pedestrian bridge in Pittsburgh.  When I started my project of walking the bridges in Pittsburgh, I realized what a ridiculous thought that was.  Pittsburgh has many pedestrian bridges, but until the new one was built, I never heard anyone talk about any pedestrian bridge in the city.  Many of these pedestrian bridges are not particularly attractive and are not in high traffic areas.

Shadyside has one of these hidden pedestrian bridges.  The bridge connects Graham Street across the busway and railroad tracks.  The only reason I know about this bridge is from riding buses on the busway.  Walking down Graham from Centre Ave (a busy corridor lined with businesses, churches and a hospital and used by several major bus routes and lots of cars), I was impressed how quiet and peaceful the residential area between Centre and the busway was.  That is until a train comes by.

As I walked across this bridge, I wondered why it was there.  There is a vehicular bridge with sidewalks on both sides across the busway a block in either direction.  There are eight other roads between this bridge and the Penn Ave Bridge that end at the busway and have neither a vehicular or pedestrian bridge connecting them to the other side of the busway.  In my walk, I speculated that perhaps it was put in to connect the residents on the north side of the busway to places of work on the southern.  This was based on the fact that there was a large building on the southern side that now houses the Shadyside Boys and Girls Club (photo below).

When I got home I went to PGHbridges.com, which I have used whenever I’ve had questions like this about the origin or design of Pittsburgh bridges.  However, for some reason this website ignores many of the bridges over the busway.  In looking up some of the bridges that PGHbridges.com misses, I found several other bridge websites that list and identify many of the bridges in the city, but none of them include the Graham Street Bridge, not even the National Bridge Inventory Database.

So I turned back to my favorite resource–the G.M. Hopkins maps.  I also went to the image collection on Historic Pittsburgh, the parent site for the Hopkins maps.  In the image collection I found one photo from 1908 of the bridge under construction.  The 1904 and 1911 maps show the area immediately adjacent to the bridge as all residential.  The building that is now the Boys and Girls Club does not exist.  All I’m left with is speculation at this point.  However, there is a school a few blocks from the southern end of the bridge and in between 1904 and 1911 another church was built a couple blocks north of the bridge.  There already was a large church a block from the site of the newer, smaller one.  Perhaps, the bridge was built to facilitate school students and church goers to get to their respective destinations.

Based on the way the bridge is depicted on the 1911 map and the 1939 map, I suspect the bridge may have been rebuilt since 1908.  At the very least the stairs were replaced.  The southern steps are drawn as coming straight out from the bridge to the road, but today the stairs are perpendicular to the line of the bridge and Graham Street.  The northern steps are drawn perpendicular to the bridge and facing the same direction the southern steps face today.  However, the steps I walked are switchback style, with the upper portion facing the opposite direction depicted on the 1939 map.

Tower Bridge

Posted on by

The last bridge in London I walked over was the Tower Bridge.  It is by far the most elaborate bridge across the Thames.  I had assumed it was also the oldest of the bridges I walked in London.  It turns out that this was a false assumption.  The current Tower Bridge was built in the 1890s.  According to the dates I found online, Southwark Bridge (see Aug 5 post)  is the oldest existing bridge I walked having opened in 1819.

The Tower Bridge is the last bridge across the Thames before it empties into the sea.  The view downstream gives some indication of this as there are no bridges in sight and the views from all the other bridges showed either another vehicular bridge, underground bridge, or pedestrian bridge.  That the Tower Bridge is the end of the bridges over the Thames is somewhat surprising to me because as the crow flies the mouth of the river is nearly forty miles away and as the river flows is even farther.  There are some tunnels under the river between the Tower Bridge and the sea, including at least one pedestrian tunnel.  I considered walking the pedestrian tunnel, but the idea of walking through a tunnel under a river seemed long, dark, and scary, and as I had already walked myself off my feet, I chose not to.

Some of the oldest parts of the city are near the Tower Bridge.  The northern shore is where the infamous Tower of London is located.  The Tower itself was built in 1078.  Crossing the bridge and turning right are several very narrow, medieval-like lanes.  Yet right near this old fabric is a very new development, situated almost directly across the Thames from the Tower of London, which from this view seems to include the controversial Shard skyscraper.  The Shard is located near the end of the London Bridge so I believe there must be some separation between the new buildings in the foreground and the skyscraper.  I understand that there is some controversy over the building as many people believed it was too close to the older fabric of the city where they wanted to maintain the historical building heights.  In the midst of the historic neighborhoods I observed this skyscraper looms up as the current tallest building in Europe.  According to an article about the official opening of the building on July4, one of the many features of this building is “double-decker lifts.”  I feel like that is the kind of thing that I’m going to have to see it to believe it.  How would a two-story elevator work?  And why would you want a two-story one?  I think it would only complicate things.

So ends the story of my journey walking across 13 bridges in London.  Hope you’ve enjoyed it!  For those interested in bridges, stay tuned as I continue to walk bridges in Pittsburgh and other cities.  For those interested in London, I plan to post about the adaptively reused churches I found in London in the near future.

Bridge Safety

Posted on by

The first time I walked across the Birmingham Bridge was before I came up with the idea of walking all the bridges in Pittsburgh.  I was going to an event on the South Side and according to the bus schedule, the best method for getting to this event was to take one of the Fifth Avenue buses to the Birmingham Bridge and walk across the bridge and down a few blocks on East Carson Street to the event.  I was quite dismayed when I got off the bus and saw that there was no sidewalk across the bridge–it turns out there is a sidewalk but it only connects to Forbes Avenue which is significantly lower than Fifth Avenue at this point.  Fortunately, there is a bike lane, clearly marked with a buffer zone across the bridge.  I kept as far to the right as I possibly could, hoping that cars recognized and honored the bike lane (I have noticed this is an issue for drivers in Pittsburgh at least in some areas), and headed across.  Nearly a quarter mile from Fifth Avenue, a ramp comes up from Forbes Avenue with a sidewalk.  I climbed over the cement barrier and crossed the core of the bridge on the sidewalk.  However on the southern half of the bridge, the sidewalk goes down a set of steps and comes out between the back of a parking lot and the underside of the bridge.  This seemed like a potentially unsafe place for a lone pedestrian, so I climbed back over the barrier and finished crossing the bridge as I had started, separated from the cars by only the painted lines of the bike lane.

I have walked this bridge a few times since then, employing this same method every time.  I have also observed other pedestrians using a similar method, though some don’t bother climbing over the barrier onto the sidewalk when that becomes an option.  This is truly the case of a bridge that may be pedestrian accessible, but is not at all pedestrian friendly.  In my post “One River Down,” I mention that Highland Park Bridge, Washington’s Crossing Bridge, and the 62nd Street Bridge are less than pedestrian friendly.  The Birmingham Bridge beats these bridges as the least pedestrian friendly bridge I’ve walked in Pittsburgh to the point that it is potentially unsafe for pedestrian use.

While the bridge is designed so that pedestrians can use a buffered sidewalk across the length of the bridge, the access points to this sidewalk are not convenient.  I discuss in “Taking the Long Way Round” that there are times and situations when pedestrians will go out of their way, but the Birmingham Bridge sidewalk does not meet them.  The northern access point is in a hollow surrounded by vacant or industrial-use lots and passes under several ramps/bridges/elevated roads carrying an interstate before reaching the level of the bridge.  Also there is no easy way to get there from Fifth Avenue at the bridge.  A pedestrian has to go down a block to a road that connects Fifth and Forbes avenues and then come back down toward the bridge to reach the sidewalk for it.  There is no incentive for a pedestrian on Fifth Avenue to go so far out of their way when the bridge is right in front of them.  The staircase at the other end of the bridge that I mentioned earlier makes about as much sense as this end’s inaccessible sidewalk access.  Not to mention that the staircase excludes anyone using a wheelchair from access to the sidewalk (it looks like there used to be a ramp on this end as well, but it is now sealed off and cut off).

What is a Bridge? Pittsburgh Edition II

Posted on by

When I wrote the first “What is a Bridge?” post, I felt confident that Merriam-Webster’s definition of a bridge, “a structure carrying a pathway or roadway over a depression or obstacle,” was sufficiently explicit to exclude ramps.  However, while crossing the Penn Avenue Bridge in East Liberty I found a new structure to challenge the definition of a bridge.

The former bus ramp from the former Penn Avenue (Bus) Station to the (not former) East Liberty Busway Station meets the above definition of a bridge as it carries a roadway over the obstacle presented by the railroad bordering the busway.  On the other hand, it also meets the definition of a ramp, “a slope or inclined plane for joining two different levels,” as the busway is significantly lower than most of the surrounding area.  So, is it a bridge or a ramp?  It almost feels like asking is a tomato a fruit or vegetable? or perhaps even which came first, the chicken or the egg?  Are these equally impossible questions to answer or is it rather the case that there are exceptions to every rule?  There aren’t always easy or straight-forward answers.  I suppose in this case the structure is both a bridge and a ramp.

Perhaps a way to answer the question a little more specifically is to look at the way it is used.  In its previous use, the point of the structure was to get buses down onto or up out of the lower busway level.  While it was used in this fashion, I’d say it was more a ramp than a bridge.  There is a future plan for it to be turned into a pedestrian bridge to transport pedestrians safely across the railroad and busway to the busway station (see Busway Bridges: East Liberty).  At that point, in function the structure will be more of a bridge, though I suppose the ramp end will still function as a ramp to provide an accessible route to the station.  Whether it is a ramp or a bridge, I did not walk it yet as it is not currently designed for pedestrian access.  After its conversion is complete in the next couple years, I will come back to walk it.

Taking the Long Way Round

Posted on by

This week while I was walking some more bridges, I witnessed a fascinating phenomenon. I had an architectural design class a few years ago where we had an assignment to create a theoretical “intervention” for an assigned two block area of Pittsburgh (which coincidentally included a bridge).  Several of my classmates noticed in observing the area a significant number of j-walkers and so designed interventions that were pathways going over or under the road to stop pedestrians from crossing the road dangerously.  The reaction that I, the professors and other reviewers had to these projects was the theory and design is nice, but no one is going to go out of their way to climb up or down just to cross the road.  Similarly to this was a conversation some classmates of mine had about the paths pedestrians created across the school’s lawn.  These paths were formed because the pedestrians recognized that the shortest distance between two points is a straight line, yet every year for many years the school insisted on replanting the grass on these paths. If I remember correctly the school eventually gave up on this and instead of replanting the grass they paved the paths.

The phenomenon I witnessed this week was a pedestrian contradicting all the observations above.  I was walking several of the bridges over the busway in the East End neighborhoods.  As I walked to the Highland Ave Bridge, I was behind another pedestrian who looked like he might have been on his way to work.  He continued straight on the road while I climbed the steps pictured above to cross the bridge.  After I crossed the Highland Ave Bridge I crossed through the EastSide parking lot to cross the new pedestrian bridge.  As I approached this new bridge, I crossed paths with the man I had been walking behind.  He had crossed the pedestrian bridge and was now doubling back to get to his location.  The shortest route for him would have been to cross the Highland Ave Bridge; instead he made the choice to go out of his way and cross the new pedestrian bridge instead.  Apparently my architectural design classmates were not as far off as I thought–given an attractive enough alternative pedestrians will go out of their way.

The new pedestrian bridge is probably the newest bridge in Pittsburgh, being less than a year old.  I had been waiting for it for over two years before it finally opened.  Shortly after it opened I took the opportunity to walk across it for the first time and was very disappointed.  I thought it looked incredibly ridiculous and with the planters on either side I didn’t feel like I was on a bridge.  I think I had imagined it as something a little closer to a swinging bridge that this heavy and solid construction.  However, the incident this week with the pedestrian has caused me to reconsider this bridge.  Comparing this bridge to the Highland Ave Bridge, I have to admit it does have many good points.  Though I still think the pedestrian bridge leans to the ridiculous, it is much more pleasant looking that the Highland Ave Bridge.  While crossing the Highland Ave Bridge, I can’t help wondering if the wooden planks that make up the sidewalk are still strong enough.  What if the wood has become rotten or termites have eaten away its integrity?

Given the proximity of these two bridges (they are about a block apart) I don’t blame the man for walking a little bit out of his way to cross the pedestrian bridge instead of the Highland Ave one.  The one complaint I have left about the new pedestrian bridge is the enclosed, caged feeling it has.  While it certainly is the most dressed up caged bridge in the city, it is still a cage.

Washington’s Crossing Bridge

Posted on by

I walked the 40th Street Bridge last fall after having taken a tour of the Maxo Vanka murals at the St. Nicholas Croatian Catholic Church (pictured above).  Two years after having come up with the idea of walking all the bridges in Pittsburgh, this one was the first that I documented (side note: the camera I had at that time produced pictures of significantly less quality than my current camera).  While the bridge itself was fine for walking across, the approach to it was quite intimidating, so much so that if there was a bus easily accessible and going in the direction I wanted, I would have chickened out and taken it instead.  Between the church and bridge I had to cross through an active road construction zone, cross more than one fast past road, and then walk up a small strip of a highway exit ramp covered in debris and just barely wide enough for passing the people coming the other direction.

The other end of the bridge connects to Lawrenceville and is much more pleasant as it immediately connects to a residential area and there is a little parklet that is designed to encourage pedestrians at one corner.  The large building in the middle of the frame above is Arsenal school, behind which is Arsenal Park.  Both sites were named after the Allegheny Arsenal located on this site during the Civil War, which played a significant role in the war and where there was a major explosion that killed many of the female workers.

On the bridge itself are seals.  I did not look closely at them as on this, my first official walk across a bridge, I was mostly concerned with the views from the bridge and not the bridge itself.  According to PGHbridges.com these seals are the seals of Allegheny County and the thirteen original colonies repeated up and down the bridge.

The downstream view above looks out over the forested northern end of Herr’s Island toward downtown.  As I mention in the Converted Railroad Bridge post, Herr’s Island has been renamed Washington’s Landing, in honor of George Washington’s crossing of the Allegheny River.  Apparently the official name of the 40th Street Bridge is Washington’s Crossing Bridge, which I was not aware of until looking it up online.  In the cases of the other bridges with double names such as each of the Three Sisters Bridges (see June 14, June 21, and June 22 posts) and the R.D. Fleming/62nd Street Bridge (see July 24 post) both names are used interchangeably, but I have only ever heard this bridge called the 40th Street Bridge.  As the person who commented on the Converted Railroad Bridge pointed out, the island renamed Washington’s Landing wasn’t actually where Washington landed.  PGHbridges.com has a somewhat detailed account of what might have happened when Washington crossed the Allegheny according to which the island he and Christopher Gist landed on after Washington fell into the river was actually on the southern side of the river (Herr’s Island/Washington’s Landing is on the northern side).

Up until this point on the Allegheny River, both sides of the river are part of the City of Pittsburgh.  Now the right-hand side of the river in the upstream view above is Pittsburgh while the left-hand side belongs to other municipalities.
