What is a Sign?

Posted on by

My day job for the last decade is working with zoning ordinances. *Yawn,* right? Except I find it surprisingly intriguing. For example, when I visited Grove City in 2022, I was in the middle of writing new model sign regulations for zoning. The puzzle pieces for this effort included incorporating Supreme Court rulings on the constitutionality of sign regulations and making the regulations easier to understand and follow.1 So signs were already on my mind when I encountered Grove City’s parking sculptures and my brain exploded.

Besides the century-old battle between planners and billboard companies, the most difficult thing about sign regulations is the definition of sign. Art cannot be regulated by zoning, but signs can. However, there is a lot of grey between art and sign. Grove City exemplifies that grey area.

Grove City has a series of outdoor sculptures that incorporate directional signage for public parking areas. Based on a strict interpretation of Pittsburgh’s definition of sign (which interpretation frequently got me into arguments with my boss when I was zoning staff for Pittsburgh), the minute any component of a piece of artwork contains a sign, the whole piece of art becomes a sign (see Pittsburgh’s Zoning Ordinance Section 919.01.C.1). The phrase “or any structure designed to carry the above visual information” supports my interpretation that Grove City’s parking sculptures would not be permitted in Pittsburgh because they would not comply with the sign regulations.

Fortunately, Grove City’s zoning ordinance measures a sign only on the “separate individual letters, words, or graphic elements on the background” (see Grove City Zoning Ordinance Section 702, page 72 of 84 in the PDF). As the structure doesn’t count in the calculation of sign area in Grove City, I can now understand how parking sign sculptures could be created without violating their own ordinance.

If you are a frequent visitor to urbantraipsing, you know I don’t typically take selfies. However, I did with the first parking sculpture I encountered in Grove City to provide a sense of scale. These are substantial structures. I am standing in the selfie…and, for those who don’t know me in person, I am 6 feet tall.

  1. I succeeded in creating a model ordinance that balanced brevity with thoroughness and usability with constitutionality. Economy, PA, (Chapter 180, Article XIV) and McCandless, PA, (Article 1305) are two of the municipalities that have adopted this ordinance to their specific needs. ↩︎

Grove City Bridges

I bought my first car in 2021. It ended up having a lot of problems. The first time I tried to drive to Erie, it started shaking like it was going to spontaneously break apart into a million pieces, just like a cartoon. Instead, it went into limp home mode and I turned around at the next exit, which was the middle of nowhere. After several repairs and a period of no further incidents, the following year I was ready to try again. But first, I tested the car to see if it could handle Rt. 79.

I knew of Grove City as an exit about halfway to Erie and as the closest outlet mall to Pittsburgh. I decided to aim for the actual Borough of Grove City1 as a destination to explore while testing my car’s ability to handle the speed limit and hills of Rt. 79. Naturally, since I arrived safely and knew nothing about the town, I set out to walk the bridges.

A town of 2.7 square miles and less than 8,000 residents, Grove City has several bridges over Wolf Creek and elsewhere. Unfortunately, the town’s premier pedestrian bridge, Rainbow Bridge (pictured above), was closed due to construction activities in the area. I discovered a second, unmapped pedestrian bridge over a small tributary to Wolf Creek, which I crossed only to see a sign on the other side claiming the bridge was not a throughway and directing people to use the sidewalks on the street to reach Grove City College’s main campus.

While the bridges themselves were structurally uninteresting, except for the Rainbow Bridge, I visited a throughout cross-section of town in walking them….which is the point of my bridge walking habit. My path took me through the college campus, the now less prominent industrial area, the large homes built for the boss class of the industries, the small homes built for the industrial workers, and the business district, both the car oriented portion and the historic portion. There are several bridgeless neighborhoods that I did not visit, but even without them, I learned a lot about the town in a short space of time.

2024 Bridge Disasters Actual and Pending

Posted on by

Bridge accidents is a common theme this year. The most significant was the collapse of Baltimore’s Francis Scott Key Bridge in March 2024 after being struck by a malfunctioning container ship. However, other accidents happened to bridges in the Pittsburgh area. Weeks after Baltimore’s bridge collapse, the Sewickley Bridge, a few miles downriver from Pittsburgh, closed for a day after being struck by runaway barges (WTAE, April 14, 2024). Then, in August, a dump truck struck an unused railroad bridge in Pittsburgh. The road underneath closed temporarily while the obsolete and now damaged bridge was removed. The adjacent, active railroad bridge remains. (WTAE, August 16, 2024)

Meanwhile, Pittsburgh continues to preemptively close bridges or restrict traffic to reduce the chances of another bridge collapse. The most recent of these is the full closure of Panther Hollow Bridge announced October 19, 2024, with immediate effect. It is called a temporary closure while the City of Pittsburgh figures out what it needs to do for the bridge. (Mayor’s Press Release, October 19, 2024) Other recent “temporary closures” of Pittsburgh bridges have turned into sporadic periods of closure and opening (Swindell Bridge) or a years-long closure while funding is found and repairs are implemented (Charles Anderson Bridge).

Another common restriction we are seeing in Pittsburgh bridges is sidewalk closures while vehicular traffic remains unaffected. Pittsburgh’s South Negley Avenue bridge is one of the bridges in town that is poised as a pending disaster. In acknowledging the structural issues of this bridge, the west sidewalk was closed in 2022. However, I noticed that by July 2023, the barriers on that sidewalk were pushed aside and it wasn’t clear if that was an official move or if pedestrians had taken matters into their own hands. Then, in June 2024, first the eastern sidewalk was closed with a temporary protected pedestrian pathway installed in the car lane (Mayor’s Press Release, June 6, 2024) and then, a week later, the western sidewalk was again closed (Mayor’s Press Release, June 17, 2024). Why this “safety” measure is helpful is beyond me as this bridge has been earmarked for replacement for years pending funding and access issues. Also, the Smithfield Street Bridge sidewalk always has rusted out holes showing the river flowing below that eventually get patched without closing the sidewalk.

Funding Bridges

Posted on by

Bridges are a vital connectors that enable us to move around as we live our lives. Frequently, we don’t even realize there’s a bridge there…at least not until there’s a bridge disaster. Over the last few years, there have been several bridge disasters, some due to accidents, like the collapse of Baltimore’s Francis Scott Key Bridge in March 2024 after being struck by a malfunctioning container ship, and some due to deferred maintenance, like the collapse of Pittsburgh’s Fern Hollow Bridge on an icy, cold morning in January 2022.

We have seen recently that when there is motivation, the missing links caused by bridge disasters can be repaired in record time. Pittsburgh’s Fern Hollow Bridge was completely rebuilt and opened to traffic 11 months after collapsing, instead of the usual multi-year process to design and build a new bridge. In Philadelphia, when an elevated section of I-95 collapsed after an accident in 2023, the repaired section reopened to traffic 12 days later, compared to 26 days for a similar situation in Oakland, CA. (PBS News, June 23, 2023)

Despite President Biden’s repeated request to Congress to expedite funds to replace Baltimore’s Francis Scott Key Bridge, Republicans in Congress are possibly motivated to delay so that President-elect Trump will get the credit for rebuilding this crucial transportation link. (Fox News Baltimore, November 8, 2024; WCBM, November 8, 2024) Unfortunately, Trump does not have a good track record for funding bridges.

It can be easy to overlook during the buzz of election season that there is often a delay between when a law is signed or a policy adopted and when the effects of that law or policy are felt. Bridges encapsulate that well. The memorable moments are when a bridge closes or collapses (typically viewed negatively) and when a bridge reopens (typically viewed positively). The moment when funds are allocated, the moment enabling a bridge to reopen at a later date, is not often remembered.

For example, it was front page news when the new Greenfield Bridge reopened in 2017, when Trump was President, but the funding that constructed the bridge was allocated when Obama was President. Similarly, the Charles Anderson Bridge has been closed to traffic for most of President Biden’s term in office, to the annoyance of many, but that is also when the funds were found to rehabilitate the bridge expanding the life of this historic bridge by decades. However, the reopening is projected to be in 2026, in the middle of Trump’s second term as President.

Assuming two years as the average time from funding to reopening on bridge reconstruction and rehabilitation projects, I pulled the Federal Highway Administration’s numbers for bridge construction and rehabilitation in Pittsburgh that would have been funded under the leadership of Presidents George W. Bush, Barack Obama, and Donald Trump. (FHWA InfoBridge) Given the delay between funding and completion, it is too early to measure the impact of funding under President Joseph Biden’s leadership.

Bush: 36 bridges total = 4.5 bridges per year

Obama: 76 bridges total = 9.5 bridges per year

Trump: 9 bridges total = 2.25 bridges per year

Bridge maintenance and repair rarely happens without support from federal funding. When the bipartisan infrastructure bill passed under President Biden’s leadership runs out of funds, or those funds get diverted to Project 2025, I am skeptical that new funding for bridges will be found under the leadership of President-elect Trump. Therefore, I expect more bridge disasters or, at the very least, more indefinite bridge closures in the coming years.

Mid-Hudson Bridge – Bridge Music

Posted on by

The Mid-Hudson Bridge has a unique additional feature. In 2009, Joseph Bertolozzi used the bridge as the sole instrument in his sound-art installation Bridge Music (see Bertolozzi’s official website for more information). There are two listening stations on the bridge, one at each pier, and those driving across the bridge can also access the music on their car radio. The full Bridge Music is available on CD and Bertolozzi has several YouTube videos of the music. Below is a sample of the music I captured in a video with views of the Hudson River and the two bridges (the Walkway Over the Hudson is the second bridge).

Half a mile downriver from the Walkway Over the Hudson (slightly closer as the crow flies) is the Mid-Hudson Bridge, so named for being halfway between New York and Albany. After being completely exposed to the noonday July sun on the Walkway Over the Hudson, I learned the relief of shade that can be had on a bridge, particularly when it incorporates some truss-like structure like the Mid-Hudson Bridge. I remember being completely in the shade while walking the Manhattan Bridge, but as that was in late December it had a completely different effect.

Taking in the Mid-Hudson Bridge added significantly to the length of my walk, but was worth it for the shade and the ability to add another bridge to my ever-growing list of walked bridges. I also encountered signs for “Bridge Music” on my way to this bridge which intrigued me and which I’ll explain further later.

Once again, additional fencing is provided on the portion of the bridge that crosses over the railroad tracks. Other than that pinch point and one or two other pinch points, my photographs suggest to me that this was a very pleasant bridge to walk. And overall, I think it was, but I was quite spooked by the number of signs warning pedestrians not to aggravate the nesting peregrine falcons on the piers. It wasn’t clear from these signs what behaviors would be sufficient to aggravate these predators, but I took the signs to mean that these birds were more sensitive than the ones found on tall buildings in Pittsburgh and curtailed my observations of and from the bridge accordingly.

I also tested out taking video of a portion of the walk of the bridge. This is something I have been considering as another way to share the experience of bridge walking with my readers. The video is below the sample of photographs. As I am holding my phone in my hand to take the video, there is a little bounce from my gait and some other slight stability issues.

Walkway Over the Hudson

Posted on by

I don’t remember how I first heard about the Walkway Over the Hudson, but it was several years before I developed the habit of walking bridges. Even at that time it sounded like a cool place to check out. Once I became a bridge-walker, it became a must-experience site. Over a decade later, I finally walked the Walkway Over the Hudson.

The Walkway Over the Hudson crosses the Hudson River at Poughkeepsie, NY. It opened in 1889 as a railroad bridge. It closed in 1974 after being damaged by fire and reopened as a renovated pedestrian bridge in 2009. It is both a National Historic Civil Engineering Landmark and on the National Register of Historic Places. At 1.28 miles it claims to be the longest pedestrian bridge in the world.

It is also 212 feet above ground or river level. In discussing my experience of climbing to the top of St. Paul’s Cathedral in London, I glossed over the fact that I almost didn’t reach the top due to my discomfort with heights and instead focused on the fact that claustrophobia almost prevented me from coming back down. Proportions and railing heights have a significant impact on whether I can manage heights. The Whispering Walk inside the base of the dome in St. Paul’s was too narrow and enclosed for me to handle the height above the floor (98 feet). The Walkway Over the Hudson, on the other hand, was quite wide having once carried two railroad tracks side-by-side. And so despite being more than twice as high up as the Whispering Walk, I did not experience much trouble with the height. I was more concerned about the possibility of the wind tearing my phone/camera out of my hand and over the edge.

Despite the potential damage that objects falling off the side of the bridge could cause, extra high barriers to prevent that are only located over the railroad tracks. As I’ve discussed in previous posts, some bridges have extra fencing only along portions of their walkways, typically over railroads and sometimes over automobile roads. The extra fencing on the Walkway Over the Hudson is from a time after it was common to curve the top, creating a cage-like feel, but before the need for extra height was incorporated into the design of the bridge itself.

There is no shade on a deck-truss bridge 212 feet off the ground. On a hot, July day, you feel the full force of the sun when taking such an exposed 1.28 mile walk starting at 11:30. If I hadn’t discovered that there was another bridge that I could walk across, I probably would have opted to take the shuttle back.

Vancouver Bridges

I can’t believe I never posted anything about my 2016 Alaskan cruise trip. It was one of my top 3 monumental trips, up there with my first train trip to Colorado (8th birthday) and my first international trip touring England and Wales (14th birthday). By the time I was 10, I decided that I would take an Alaskan cruise for my 30th birthday. By my mid-20s, I realized that wasn’t going to happen, but then when I was 29, my friend and her family were planning their annual cruise and picked Alaska. I asked to join them and a few weeks after my birthday celebrated my 30th while cruising in Alaska.

The trip was amazing. I gathered enough materials and felt excited enough about what I saw and experienced to be energized to share the trip with my readers. However, as soon as I got home from the cruise, life overwhelmed me. The months after the cruise were when I first learned to hate my job, I was house hunting, and my appendix burst. This plethora of life distractions prevented me from blogging.

Now, however, I have an opportunity to catch up on the trips and traipses that I intended to blog about but never did. I’ve had Long COVID since November 2023, which has reduce my ability to do new urban traipsing, but on days when I’ve had energy and inspiration, I am revisiting former trips to share with you. Through the rest of this year and throughout 2025 (and maybe beyond), I’ll be sharing these retrospective reflections of my past travels.

My 2016 Alaskan cruise started in Vancouver and ended in Anchorage. I added a few nights on either end to allow me to explore those cities. Naturally, I found my way to bridges in Vancouver. At this point in time (8 years after the fact), I don’t remember which was the instigating factor, the bridges or the store. Whichever inspired me first, I took advantage of walking over the Granville Bridge to visit Hammered & Pickled on Granville Island and returning by way of Burrard Street Bridge. I chose Hammered & Pickled for my destination to satisfy my curiosity on what kind of pickled they covered: pickled vegetables, pickled metal, or pickled people. It turned out it was a silversmith selling handcrafted jewelry.

Oddly, from my walks across the Granville and Burrard Street Bridges to and from Hammered & Pickled, I took more photos of the less structurally interesting bridge. This may have been the impact of being tired and dehydrated on the return or of the construction on the Burrard Street Bridge. However, the bridge that I took the most photos of in Vancouver was one I didn’t walk: the Lions Gate Bridge. I biked the waterfront trail underneath this bridge, rode over it by bus on the way to Grouse Mountain, and later passed under the bridge as the cruise ship left the Vancouver harbor.

Buffalo Waterfront I

Posted on by

Waterfronts are often the reason why cities exist where they are. However, in the last 50-75 years, we have built barriers cutting ourselves off from these natural amenities. I’ve written about the experience of trying to reach waterfronts in Erie and Chicago. Buffalo echoes those experiences, but with a happier ending.

Before making an official urbantraipsing trip to Buffalo, I had encountered the freeways around the city multiple times. The flying roadway carrying Route 5 that starts near downtown and travels over a sizable portion of the industrial area along the waterfront is a memorable piece of infrastructure. And one that I had assumed would contribute to the cutting off of the waterfront from the city.

Route 5 and I-190 meet at the southwestern corner of downtown Buffalo creating a knot of an interchange and on/off ramps that block access between downtown and the waterfront. But, beyond that point of intersection, both roads are elevated leaving open multiple pathways underneath for pedestrians, cars, and transit. They still create a psychological barrier – it never feels welcoming to pass underneath overpasses like these – but the physical connection is there. And once you pass through the barrier, there is much to see and do at Canalside.

The Flamingo’s-Eye View

Posted on by

I took an enjoyable interlude in my wanderings in Buffalo’s Delaware Park that included getting the nice lake-eye views of the Lincoln Parkway Bridge I shared last month. I wonder if Frederick Law Olmsted ever imagined something like flamingo paddle boats as a potential use of the lake he designed. I don’t know if he would approve, but I had fun stepping out of the ordinary for a hour to view the lake and the park from the flamingo’s perspective. Below you can vicariously join me on the experience in a short video or in the sample of photos I took around the lake (including one with at least 4 turtles sunning themselves).
