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 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: 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.

Bridge Collapse: Six Months Later

There was a lot of news about the bridge this month. PennDOT and the Mayor’s office held a press conference on Monday to announce that the bridge may be completed before the end of the year. This unusually fast pace is because construction is underway while the design is still being worked out. Inspired by the event, I went to Frick Park after work and explored the view of the bridge from the northern approach along the Tranquil Trail.

While the news is good for the Fern Hollow Bridge reconstruction, there were hiccups this month on the Swindell and Port Authority bridges.

Below is a slideshow of photos from my hike this month followed by the news updates on the Fern Hollow Bridge and other bridge maintenance and replacement efforts in Pittsburgh and Allegheny County.

  • The beams for the new Fern Hollow Bridge are being delivered to the site two per day, generating excitement on news and social media. (WTAE video of the first beam delivery, July 26, 2022; CBS article and video, July 25, 2022)
  • Two artists were selected to provide artwork for the new Fern Hollow Bridge (City Press Release, July 25, 2022)
  • Despite the press conference, artist announcement, and beam delivery schedule, there are no new updates on PennDOT’s project page regarding the reconstruction of the bridge.
  • Similarly, no new updates have been posted regarding the National Transportation Safety Board’s ongoing investigation into the Fern Hollow Bridge collapse.
  • 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. However, there was a press release this month asking for applicants interested in serving in any of the city’s boards and commissions.
  • WSP USA was selected to manage the City’s new Bridge Asset Management Program. (Tribune Review, July 19, 2022)
  • On Tuesday, Port Authority found a crack in one of the rails on the bridge that was just repaired. The inbound T service was discontinued for two days to enable the replacement of this portion of track.
  • On July 1, Pittsburgh’s Swindell Bridge was closed due to falling debris. The falling debris was noticed during the first phase of repairs, which was repaving the road. (City Press Release, July 1, 2022) The subsequent inspection found that the debris came from the repairs – material accumulated in one of the drainage troughs, putting unusual pressure on the trough and causing it to “tear open and spill” the debris onto route 279 – hours after I had driven under it. (City Press Release, July 5, 2022)
