From time to time, someone will ask me which Pittsburgh bridge is my favorite. I typically answer the Smithfield Street Bridge. The shape and color of its trusses are unique in a city of golden bridges. The lights gently rising and falling along the curves the the trusses create a soft reflection on the river. Walking over it placed the stress of work on the other side of the river. Walking over it, it’s best not to look down at the holes rusted through the sidewalk that reveal the rushing water underneath.
This question came up again when my family was visiting for the holidays. I had postponed my first walk across the new Fern Hollow Bridge about a week to share the experience with them. While we were walking across it, I was asked what bridge(s) I liked in Pittsburgh. While I answered that the Smithfield Bridge is probably my favorite, we had experienced that one multiple times in the past, so I started to think about what are the other bridges I find interesting that are less visible than the Smithfield Bridge. This spurred an impromptu driving tour of bridges in Pittsburgh.
We went from the Fern Hollow Bridge to the Greenfield Bridge, as the last time we were all in Pittsburgh together we watched the cloud of dust from the implosion of the former bridge through the trees of Schenley Park. We passed the Hot Metal Bridge, Birmingham Bridge, and South 10th Street Bridge before passing through the Armstrong Tunnel for the fun of it. That positioned us to encounter the CAP – which is one of those bridges that doesn’t look like a bridge – on our way toward the Allegheny River. I added an extra turn so that we could pass over the 28th Street Bridge – the only through truss bridge over the busway – before crossing the 31st Street Bridge (my other favorite bridge to walk, except for the fact that it is out of the way). We got out of the car at this point to walk the pedestrian/bike trail bridge to Herr’s Island. While that was the end of this unofficial tour, we did pass by the 40th Street Bridge and cross the R.D. Fleming or 62nd Street Bridge to complete our loop.

Irony? Serendipity? A sign I’ve walked too many bridges? It’s been one year since Pittsburgh’s Fern Hollow Bridge collapsed into Frick Park and another important arterial bridge is now closed and I am once again unable to fully explore due to another foot injury.
Shortly after the Fern Hollow Bridge collapsed, photos of temporary wires holding up the Charles Anderson Bridge supplementing the original metal structure that had rusted all the way through in places peppered social media and made the news with the question of would this be the next bridge to collapse? On February 1, 2023, the Charles Anderson Bridge was “immediately closed” to vehicular traffic (press release). Those with fully functioning limbs are still able to walk or bike across or under the bridge – it passes over another one of Pittsburgh’s major parks (Schenley Park).
The bridge was closed to facilitate interim repairs that may take four months. The bridge has been slated for a full rehabilitation for several years (see the City’s project page for more). The original projection was that this project would be funded this year, but according to a press release from the Mayor’s office on February 2, the expected funds have been delayed until 2027 and the City is looking for ways to expedite the funding.
Also, along the lines of serendipity, I happened to be browsing my copy of Bob Regan’s “The Bridges of Pittsburgh” (2006) this week for unrelated reasons and came across the section “Bridge Disasters.” The section opens with the statement: “Although Pittsburgh area bridges are quite safe and there has been an absence of bridge problems in modern times, this was not always the case.” (page 50) After identifying several of the bridge disasters from pre-modern times (summarized below), he ends this section with “Since that time [1927] there has not been a bridge collapse in the Commonwealth of Pennsylvania and there has never been a collapse of an operating bridge. However, this record was somewhat blemished in late 2005 with the collapse of a portion (one side girder) of a bridge over I-70 near Washington, PA.” (page 51) Of course, any updated version of the book will now have to strike this claim due to the 2022 collapse of the operating Fern Hollow Bridge.
Driving over the new Fern Hollow Bridge this week, it looked in pretty much the same condition as in December with one lane of traffic in each direction and one shared path open. There were several bikers and pedestrians using it while we crossed during the latter part of rush hour.
Bridge disasters highlighted in “The Bridges of Pittsburgh:”
1845 – The original Smithfield Street Bridge burned down
1851 – The 16th Street Bridge burned down
1865 – Two spans of the 16th Street Bridge was washed away in a flood
late 1880s – The 6th Street/St. Clair Street Bridge burned down
1903 – The Wabash Bridge collapsed during construction
1918 – The 16th Street Bridge burned down (again)
1921 – The 30th Street Bridge burned down
1927 – The Mount Washington Roadway Bridge collapsed during construction

Below are the news updates on the Fern Hollow Bridge and other bridge maintenance and replacement efforts in Pittsburgh and Allegheny County.
The proposed artwork for the new bridge is among the elements not yet completed. I didn’t find any new information on this since the NextPittsburgh article of September 26, 2022, that I cited in the December update.
PennDOT’s project page regarding the reconstruction of the bridge has not been updated since March 2022, except to add a sentence at the beginning to say that the bridge is now complete and operational, despite the fact that it is not fully open yet due to ongoing work/finishing touches.
The National Transportation Safety Board’s ongoing investigation into the Fern Hollow Bridge collapse was updated on January 26, 2023, with details of what has been investigated to date including photos of some of the parts of the collapsed bridge. It also now contains a link to a preliminary docket of materials that have been gathered in the investigation. They are still working out the cause of the collapse and recommendations to prevent such incidents in future.
The City created a Commission on Infrastructure Asset Reporting and Investment in March 2022, but this commission has not been added yet to the city’s website listing all Boards and Commissions and I have not seen any announcements of any appointments to the new Commission.

The closure of the west sidewalk of the South Negley Avenue Bridge doesn’t phase some people as they by-pass the barriers and continue on their way, in fact one of the barriers had been completely moved aside the last time I drove across the bridge, presumably by someone who found it in their way.

Map of bridges discussed in the Bridge Collapse series:
Six months after Pittsburgh’s Fern Hollow Bridge collapse, PennDOT and the Mayor’s office announced that the new bridge would probably open before the end of the year. The ribbon cutting for the new bridge was held on December 21 (Governor Tom Wolf News, WPXI, Pittsburgh Business Times) and the bridge opened to partial traffic the following day. There is one lane of traffic open in each direction and one “shared path” open on the south side of the bridge. Work on the bridge will continue through the spring.
The initial designs showed a bridge designed for highway vehicle traffic with pedestrian and bicycle access tacked on in a thoughtless way. Despite public outcry and professional push-back, the initial designs went primarily unchanged. As the bridge is not fully open, there is a chance that in execution it won’t be as bad as the initial design suggested, but it’s not off to a promising start.
The shared path on the south side – the one that’s now open – connects to sidewalk on the east side of the bridge and to the trails in Frick Park on the west side. There is no existing sidewalk to continue walking along Forbes Avenue to Squirrel Hill. While this path is unusually wide for a bridge, it appeared to be just a sidewalk when I visited it this week. I adopted the term “shared path” based on the videos of the ribbon cutting, which claimed that’s what it is. Perhaps there will be signage added eventually that bikes are also permitted, but I didn’t notice a way for bikes to get up onto this path from the road. While I’m clearly judging this bridge already and finding it wanting, I will continue to monitor its progress and will be open to finding it better than I do now once all the amenities are open and I’m no longer confronted with pedestrian dead end signs.
Below is a slideshow of photos from this month’s traipsing of the bridge followed by the news updates on the Fern Hollow Bridge and other bridge maintenance and replacement efforts in Pittsburgh and Allegheny County.

For whatever reason, PennDOT’s project page regarding the reconstruction of the bridge has not been updated since March 2022, making it a completely useless resource.

Both PennDOT and the Federal Highway Administration have interactive maps of bridges for the state and country respective, and their inspection statuses.
The final bridge in our 10-year anniversary look back at the Pittsburgh bridges and their environs is the Hot Metal Bridge. This is upriver from the Birmingham Bridge and the last bridge on the Monongahela before the big bend that hides downtown from view.
The Hot Metal Bridge was built to connect the Jones and Laughlin Steel Mill’s sites on opposite sides of the Monongahela River. With the industrial decline of Pittsburgh’s steelmaking industry in the mid- to late-20th century, Jones and Laughlin’s operations ceased over the 1980s. The first redevelopment of a portion of their property began in 1981. The redevelopment continues today.
On the south side of the river, the former site of milling operations is now the South Side Works shopping, dining, and residential area. Since 2012, the first marina in the city limits was added here and buildings under construction have opened (first photo pair), other buildings not pictured have been added.
On the north side downriver, the former site of the blast furnaces is now the Pittsburgh Technology Park containing office buildings, parking, and a hotel. The hotel was added in the last ten years as well as several other buildings outside the frame in the second and third set of photos.
On the north side upriver, the former Hazelwood Works is now the Hazelwood Green site a planned mixed-use, multi-block redevelopment. The remaining mill buildings on the site have been redeveloped as office and research facilities with the Mill 19 building visible on the left side of the river in the fourth photo pairing. The space between and around these buildings is expected to be filled in with other buildings of a variety of uses in the coming years.
The final photo pair features the former St Josaphat’s Catholic Church on the South Side Slopes, which is a building I have an eye as one of Pittsburgh’s pending adaptively reused religious buildings. This view shows another angle of the growth of the South Side Works development.
While both South Side Works and the Pittsburgh Technology Park were substantially developed by 2012, they continue to expand. On the other hand, Hazelwood Green is just beginning to be developed and is still predominantly vacant land. In another 10 years, perhaps, the upriver view from the Hot Metal Bridge will be significantly altered.

The penultimate installment of the Then & Now series is the Birmingham Bridge just upriver from the Duquesne University Pedestrian Bridge. This is a bridge that I’ve walked multiple times from necessity despite the fact that it was not well-designed for pedestrians, which I complained about in my first post about the bridge.
It would be nice to think that the pedestrian access upgrade it underwent in 2021 was in response to my complaints of the accessibility issues with the bridge design. However, the upgrade only partly resolves those issues.
On the south end of the bridge, pedestrians are no longer forced to leave the bridge and take steps down into the park. Instead, there is an option to continue along the level of the bridge. (See the first pair of photos.) This new option at first pushes pedestrians into the edge of the pavement beside the bike lane with no physical separation from the bikes or speeding cars. Once the bridge reaches the ground, a raised sidewalk appears.
On the north end of the bridge, there was no change for pedestrian’s use of the bridge (second photo pair). The options remain to walk in the painted buffer of the bike lane from where the bridge leaves Fifth Avenue or walk several blocks out of the way down the equivalent of multiple stories only to walk back up them on the sidewalk on the ramp from Forbes Avenue.
The view of Oakland from the bridge (third photo pair) shows a building that I regretted not taking photos of before it was demolished and one of the new buildings built along Fifth and Forbes in recent years. Looking downriver toward downtown (final photo pair), the new vision center as part of UPMC Mercy Hospital is clearly visible, though its coloring blends in well from this distance. Both of these views are expected to change further in the coming years with additional growth in Oakland and the redevelopment of the Lower Hill adjacent to downtown.

I first walked the Duquesne University Pedestrian Bridge as part of my 10th Street Bridge walk in September 2012. However, by that point I was walking bridges faster than I could post about them. This is one of the bridges that I hadn’t posted about until now. It is accessed by a multi-story staircase from the northern end of the 10th Street Bridge and it crosses the speedy Blvd of the Allies. Students who prefer walking (and climbing) to transit and who live or party on the South Side use the 10th Street Bridge-staircase-pedestrian bridge path to get to and from campus.
Because of this bridge’s perch on The Bluff, it has great views up and down the Monongahela River. Some of the developments that have happened since 2012 along this river are visible from this bridge. The first pair of photos show a new construction self-storage complex that was built on a vacant, but complex, industrial site. Zooming out some in the second pair, a now brightly colored set of warehouses stand out (which incidentally are next to the Highline/Terminal Way Bridge). Less clearly visible is the white smudge that is the extension into the river built by the gravel company just on the other side of the Liberty Bridge.
The most surprising thing to me on this return trip is that the new UPMC Mercy Vision Rehabilitation Center that is still under construction and looks massive from the views in my Keeping an Eye on Uptown series is not very visible from this bridge. If it had been a sunny day when I was out taking photos, perhaps the glass would have glinted a little more behind the freeway sign, but as it is, the dark spot visible under the freeway sign now isn’t much different than the dark spot from 10 years unless you zoom in close (final photo pair).

Last month’s look back at the 40th Street Bridge wrapped up the Allegheny River watershed portion of our 10-year anniversary Then & Now series. This month, we start revisiting bridges in the Monongahela River watershed.
The Terminal Way Bridge – now called The Highline – is unique in the Pittsburgh bridges I’ve walked as it is not a through-way. It is an elevated passage that connects five buildings of a former large warehouse operation. The bridge was previously a car road and parking lot. Pure speculation based on the small factoids and selection of historic photos on the Highline website suggests that at one time, this road was were good were loaded onto local delivery vehicles. Now, it is closed to all vehicular traffic and is instead an outdoor amenity space, exclusively for pedestrians and bicyclists.
While I walked over the bridge multiple times before the renovation, I was never inspired to take a photo of the parking lot that it was. I did, however, take photos of it from below which are still able to show the change from car parking to planters. They also show the change from former warehouse to a place poised to become a hip place is town.

The next bridge in the 10-year look back at urbantraipsing bridge walking is the 40th Street Bridge, which is about a mile from last month’s featured bridge: Herron Ave Bridge. The 40th Street Bridge, aka Washington’s Crossing Bridge, crosses the Allegheny River connecting Pittsburgh’s Lawrenceville neighborhood with the Borough of Millvale.
I first walked the 40th Street Bridge before I had the idea to blog about bridge walking, but as I had my camera with me, I took views from the bridge. Since then, the quality of my cameras has grown exponentially and several developments have arisen on the Lawrenceville side of the river. On the upriver side of the bridge, there is a new apartment complex, The Foundry at 41st, and a new office building, TechMill 41 (see the first pair of photos below).
On the downriver side, phase 1 of the large Arsenal 201 mixed-use development was completed on the former site of the Allegheny Arsenal famous for supplying munitions to the Union Army during the Civil War (see the second pair of photos below). The arsenal is perhaps even more famous for the accidental explosion that is identified as the worst civilian casualty of the war killing 78 people, mostly women and girls. Phase 2 of this development is well under way.
Also, on that side of the bridge, some of the new developments on Butler Avenue near Our Lady of the Angels Parish St. Augustine Church are visible including the new Capuchin Friars home (third pair of photos) and one of the new mixed-use buildings that have popped up in the neighborhood over the last 10 years.
