Bridge Collapse: Eleven Months Later

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.

  • The City announced traffic pattern changes now that the bridge is reopening, breaking up one of the smooth travel paths for vehicles trying to cross the eastern neighborhoods on a north-south axis. (City Press Release, December 22, 2022)
  • The proposed artwork for the new bridge is among the elements not yet completed. (NextPittsburgh, September 26, 2022)
  • 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.
  • The National Transportation Safety Board’s ongoing investigation into the Fern Hollow Bridge collapse was last updated in May 2022, but this was initially described as a long-term effort.
  • 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.
  • WSP USA released it’s Comprehensive Bridge Asset Management Program Report of the 147 bridges owned by the City of Pittsburgh – lots of work needs to be done on Pittsburgh’s bridges. (City Press Release, December 22, 2022; Tribune Review, December 21, 2022; WPXI, December 22, 2022)
  • The City of Pittsburgh’s 2023 Capital Budget includes limited funding for bridge repair and maintenance. (Public Source, December 5 & 22, 2022)
  • The bridge Port Authority closed to repair shortly after the Fern Hollow Bridge collapse, and then had to re-repair in July, seems to be okay now.
  • On July 1, Pittsburgh’s Swindell Bridge was closed due to falling debris. It reopened on September 1. (City Press Release, September 1, 2022; CBS, September 1, 2022; WPXI, September 1, 2022)
  • The Finland Street Pedestrian Bridge underwent an emergency demolition on October after being struck by a crane attempted to pass underneath. (City Press Release, October 7, 2022; City Press Release, October 8, 2022)
  • The City of Pittsburgh announced in November that it was going to close the east sidewalk on the South Negley Avenue Bridge (one of the bridges that the public is concerned about its highly deteriorate appearance) out of an “abundance of caution” to accommodate repairs, however, it was the west sidewalk that ended up closing. (City Press Release, November 23, 2022)
  • A public hearing was held on the Davis Avenue Bridge Reconstruction project in September. (City Press Release, September 28, 2022)

Then & Now: Hot Metal Bridge

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.

Then & Now: Birmingham Bridge

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.

Then & Now: Duquesne University Pedestrian Bridge

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).

Then & Now: Terminal Way Bridge

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.
