Arena Developments

Allentown, PA, had been on my travel list for years because of the awards and acknowledgements it was receiving from the planning community (and because I grew up near there). When I finally visited, the only thing that engaged my interest was the Liberty Bell Museum. There was a stark contrast between the cohesion and vibrancy of Bethlehem’s main street, where I stayed, and the hodge-podge of Allentown’s main street. The proportions in Allentown felt all wrong. In the core, the roads and sidewalks felt too narrow for the density and height of the buildings. At odd moments, this claustrophobic spacing suddenly opened out into large vacant plazas with buildings placed far from the road. After the pleasant surprise of Bethlehem’s tree-lined, historic business district with wide sidewalks for promenading and window shopping (and now social distancing), Allentown was a disappointment.

However, since being home, I find I have a growing appreciation for one of Allentown’s newer developments. The PPL Center gave me a sterile vibe at the time. I only glanced at the façade as I investigated the map out front with recommended lunchbreak walks and the historic building next door. From the outside, the partial attention I gave the center suggested a shopping or office complex. It wasn’t until I accidentally entered the lobby and saw the stadium seating beyond the ticket booth that I realized it was an arena. Perhaps due to my distraction at the time, it was only in the comfort of my home that I registered my shock over finding an arena that managed the rare feat of fitting into its surroundings.

Pittsburgh’s arenas have done the opposite. For decades, there was the Civic Arena that looked like a spaceship plopped down in the middle of a city spewing parking lots out from the landing center. A flagship of Pittsburgh’s Urban Renewal, it has since been demolished with the plan to rebuild the urban fabric on the site to reconnect the Hill District to downtown. The replacement arena made some attempts to fit in more with its neighborhood. It is built up to the sidewalk or, rather, the sidewalk is built up to it creating a large sea of concrete out of proportion with the sidewalks opposite. The principal street façade includes one restaurant open to anyone inside or outside the arena during normal restaurant hours, though I don’t recall ever seeing anyone eating at their sidewalk café (even before quarantine and social distancing). Instead, the restaurant feels like a weird mistake pasted onto the building’s towering blank wall.

In contrast, the street facing restaurants in Allentown’s arena are part of the reason I mistakenly identified the structure as a retail and office building. They felt like places with lives of their own, independent of special events. The plaza in front of the arena is proportional to the plaza on the adjacent corner. The building is built up to the sidewalks with the same building height and sidewalk width as the surrounding urban fabric. As a result, this arena blends into its neighborhood, such as it is.

Everyday Art – Bethlehem

While looking for churches on Bethlehem’s South Side, I discovered fun, colorful planters lining the business district’s streets. I photographed 25 that were along my path, though there were many others if I had taken time to continue wandering.

The planters are a beautification project of Bethlehem’s South Side Arts District Main Street Program. Pittsburgh gets a shout-out as inspiration for the arts work of this organization, but I think they’ve surpassed Pittsburgh with this project. While Pittsburgh has various murals and hosted a dinosaur fiberglass fundraiser during that fad, it doesn’t have initiatives to turn everyday street objects into public art canvases. I’ve enjoy stumbling across these everyday artworks in Bethlehem and Harrisburg.

The Story of the Spires – Bethlehem

While exploring Bethlehem’s bridges, my eye was caught by the numerous spires rising above the surrounding buildings of South Bethlehem. Instead of resting upon returning to the hotel, I felt compelled to go back out and take a survey of religious buildings within walking distance. Due to the topography, those on the slopes of South Bethlehem were the easiest to spot, but I also located some in Bethlehem’s historic district and in West Bethlehem. I found twenty-three buildings in all.

As with my experience in Erie, I was surprised that the vast majority of these buildings were still open for use as religious worship. Bethlehem Steel Company was the main employer in Bethlehem for most of the 20th Century. Like steel mills elsewhere in the northeast, its business declined. In the early 2000s, the company went bankrupt. This makes it seem like the town should have experienced the classic rise and decline of other Rust Belt Cities.

One of the typical landmarks of this change is an abundance of vacant or adaptively reused religious buildings. In Pittsburgh, I have found over 50 former churches and synagogues now being used for secular purposes or in the process of being converted to secular purposes. Many more are vacant and boarded. Wilkinsburg, a town adjacent to Pittsburgh, has so many closed churches that its zoning code incorporates guidelines for converting church buildings to secular uses. Homestead, PA, the former home to US Steel and the site of the famous Homestead Steel Strike, has several shuttered churches. Bethlehem’s religious buildings did not fit this pattern.

In searching for an answer to what made Bethlehem different than other steel towns, I realized that the business districts and residential areas I passed through were mostly intact. There were few vacant buildings and no vacant and abandoned grass lots. This suggested that Bethlehem did not experience the same decline as the other former steel towns that I have explored. The historical population data corroborated this hypothesis. Bethlehem and Erie experienced their peak populations in 1960; Pittsburgh and Wilkinsburg in 1950; and Homestead in 1920. In 2010, the cumulative population loss from each city’s peak was:

CityPopulation Loss
Bethlehem1%
Erie26%
Pittsburgh55%
Wilkinsburg49%
Homestead85%

The stable population of Bethlehem explains why so many religious institutions are still operating. It doesn’t explain why the people stayed when the jobs left.

I picked up Jeffrey A Parks’s “Stronger than Steel: Forging a Rust Belt Renaissance” to look for clues to what made Bethlehem different from other Rust Belt cities. For the most part, it seems to have pursued the same actions and initiatives as elsewhere. Bethlehem’s leaders even hired consultants from Pittsburgh in the 1950s to learn how to do Urban Renewal. Other similarities include the creation of a redevelopment authority, the use of eminent domain to force people out of their homes for commercial development, the building of a highway through town, and the change of traffic patterns to prioritize the regional over the local.

The one thing mentioned in Parks’s book that was different from other cities was the school district. In the 1960s, the Bethlehem School District expanded to incorporate two rural townships. These townships later became wealthy suburbs that combined with the population of Bethlehem to create a racially and economically diverse district. Parks’s implication seemed to be that the result was a school district with better funding and resources than its neighbors. Perhaps, as a result, families did not have the conversation about moving to the suburbs for better schools as their children approached school age.

A decent inner-city school district may reduce the flight to the suburbs. It also may attract new residents. Yet, I wonder if it is enough to prevent hemorrhaging population loss as a region’s major employer cuts jobs in the decades before it closes.

What is a Bridge? Bethlehem Edition II

Looking back at the original intent of the Hill-to-Hill Bridge and comparing it to its use today, I find myself asking a new question: what is the purpose of a bridge? The word bridge is often used metaphorically to describe something that brings two things together. At the same time, there is a running joke in Pittsburgh (the City of Bridges) that if it involves crossing a bridge, people would rather stay home. This conflict of ideas between a bridge as a connector and a bridge as a divider is illustrated by the Hill-to-Hill Bridge.

The Hill-to-Hill Bridge started out as a connector. A Y at the north end linked West Bethlehem and Bethlehem to the main span which connected to South Bethlehem. The ramps in-between connected the neighborhoods to the businesses on the flats by the water.* Over time, the priority on connection disappeared as the bridge was modified. Of the seven original approaches, three were demolished, one was permanently closed to through traffic, and one was changed to one-way traffic.

The explanations I came across for alterations to the bridge seem reasonable, but they do not tell the whole story.

  • Reason #1: Industry changed and shut down in Bethlehem as with other Rust Belt cities. Some of the business destinations connected to the bridge were among those that closed, removing the need for the connection.
  • Reason #2: Cars became bigger, faster, and more numerous, making it harder to navigate the tight turns on some of the approaches.

The story that is overlooked by these explanations is that in the 1960s a new highway was built from the north directly tying into the bridge. The introduction of high-speed traffic to the bridge, or to any roadway, certainly makes it less safe for local traffic.

As a result of the addition of the highway, instead of connecting the neighborhoods of West Bethlehem, Bethlehem, and South Bethlehem, the bridge funnels traffic directly toward the former steel mill, Lehigh University, and other points south. In fact, the residents of West Bethlehem are practically excluded from using the bridge to get anywhere, as the western ramp is closed to through traffic (though open to parking). To use the Hill-to-Hill Bridge to reach South Bethlehem, a resident of West Bethlehem would have to drive north several blocks to get on the highway going south. Alternately, a resident could go south by taking Spring Street, a road parallel to the western and eastern wings of the bridge, (by)passing under the main span, then skirting around the hill of historic downtown, and taking the Fahy Bridge instead.

People living and working in the historic downtown area (the Bethlehem neighborhood) are also now limited in their use of the bridge. If coming across the bridge from the south, they can take the eastern viaduct to enter the historic downtown, but to leave the area by way of the Hill-to-Hill Bridge, they would have to drive north to the same highway access point as the residents of West Bethlehem. They could alternately take the Fahy Bridge for a more direct route south.

Use of the bridge is a little easier as a pedestrian, though it is still the most challenging for residents of West Bethlehem. For pedestrians to access the bridge from the west, they would have to use the sidewalks on Spring Street, walk under the main span, and climb a towering staircase up to the sidewalks on the bridge. If they are not able to use the stairs, they could keep going on Spring Street up the hill to the eastern end of the viaduct. Once on the bridge, both the historic downtown and south side are accessible. Given the history of the bridge, I imagine that there once was a time when there were crosswalks at the intersection of the main span and the east and west spurs so that pedestrians had full use of the structure just as drivers would have had.

The shift in the bridge’s focus from local to regional traffic seems like a classic case of the Urban Renewal efforts of the 1950s and 1960s. The discussion among planners and officials in recent years is how do they undo or erase the mistakes of Urban Renewal. Pittsburgh is trying to reconnect the local by returning some one-way roads to two-way traffic and by building a cap over the highway that divided downtown and the Hill District. As I watch these developments in Pittsburgh, I wonder if there are ways to return the Hill-to-Hill Bridge to a focus on the local.

For example: The highway has to end at some point, which is currently at the southern end of the bridge. What if it were moved to the north end of the bridge? If a traffic light were introduced there, the western branch could be reopened to through traffic and the eastern branch could be restored to two-way traffic. Pedestrians would also be able to then use all the remaining approaches. Thus, West Bethlehem, Bethlehem, and South Bethlehem would be reconnected for the enjoyment of pedestrians and drivers.

This suggestion is based upon the assumption that the local community would want to be better connected by way of this bridge. Perhaps the question that should come before “what is the purpose of a bridge?” is “who gets to decide the purpose of a bridge?”


*By prioritizing connections, Clarence W Hudson, the bridge’s designer, was forced to develop a one-of-a-kind truss design to accommodate the railroad tracks beneath the bridge and the connections coming into the bridge. There is no record of this truss design being used on any other bridge.

What is a Bridge? Bethlehem Edition I

I was in the midst of trying to understand what is a viaduct when I traveled to Bethlehem, PA, with my family. One of our activities was to explore the bridges (see also Cage-free Bridges). As we walked the Hill-to-Hill Bridge, my initial reaction was “now here is a viaduct.” I hadn’t reached the point of developing a semi-clear definition for viaduct but looking at the flat roadbed supported by multiple arches over the floodplain, viaduct seemed the most appropriate word for the structure.

As we kept walking, it turned out that the viaduct was only a portion of the Hill-to-Hill Bridge. In fact, it would be more appropriately called the Hill-to-Hill-to-Hill-to-Hill Bridge. There are two approaches to the main span on the south end and three on the north end, including the viaduct and one approach permanently closed to through traffic. When the bridge was built in 1924, there were a total of seven approaches at various points along the main span. With so many components, this structure brings me back to the question of how many is one bridge?

Unlike when I asked this question of the 30th and 31st Street bridges in Pittsburgh, here the main bridge, the intersecting viaduct, and the numerous connections seem to be considered one bridge. They are together called the Hill-to-Hill Bridge while the structure in Pittsburgh has three distinct names (including River Avenue Ramp). Perhaps the deciding factor in whether it is one or more bridges is the original intent. The Hill-to-Hill Bridge was designed as a multifaceted structure whereas the 30th and 31st Street bridges were developed independently.

The best indication of the original intent seems to be the name. The Hill-to-Hill Bridge has a single name whereas the 30th and 31st Street bridges have separate names. The other examples I looked at in 2012 were the Veterans Bridge (Pittsburgh), the Fort Duquesne Bridge (Pittsburgh), and what I called the Jubilee Bridge (London).

The Veterans Bridge joins three approaches into one bridge, all under a single name. Therefore, it is one bridge, not three.

The pedestrian walkway of the Fort Duquesne Bridge was built decades after the vehicular portion but does not have a separate name. Therefore, it is one bridge, not two.

What I called the Jubilee Bridge (despite the photo I took at the time of the dedication plaque stating otherwise) is actually called the Golden Jubilee Bridges. While these bridges share the support structure of the underground’s Hungerford Bridge due to concerns about unexploded WWII bombs in the area, they have separate names. Therefore, it is three bridges, not one nor two.

Cage-Free Bridges

The summer I spent walking Pittsburgh bridges, I complained about the cages on the Millvale Avenue Bridge, the Highland Park Bridge, and the Graham Street pedestrian bridge. The narrow sidewalk and chain link fences on the first two examples and the chain link cage on the third example made me feel yucky and claustrophobic. Thanks to one of my blog followers, I recently learned that people tend to throw things onto moving objects, which is why bridges like the Millvale bridge have higher fencing along portions over roads and railroads. I still wished there was a cage-free option to meet the same goals of the bridge builders.

In Bethlehem, PA, I found just such an option on the Fahy Bridge. It is a fairly plain concrete bridge saved from the ugliness and gloom of many concrete bridges by using a functional, yet decorative, railing instead of the more common functional, yet ugly, chain link fence. This railing was installed during the 2016-18 renovation of the Fahy Bridge. Recent bridge renovations and replacements in Pittsburgh also feature more decorative railings. While the first of these new bridges in Pittsburgh tried to dress-up a chain link fence cage, the later ones are successful cage-free bridges even when they incorporate chain link fencing.* These examples give me hope that the days of caged bridges may be a thing of the past.


*Note: I have a to-do item to go back and photograph these new bridges for future posts, but no set timeline for the completion of this task.
