Greenfield Bridge Closure, Reconstruction Project To Begin Friday Night

PITTSBURGH, PA (October 13, 2015) - The Department of Public Works advises that the 94-year-old, 274 foot long Greenfield Bridge will be closed for reconstruction beginning Friday, Oct. 16, 2015 at approximately 10:00 p.m.

The bridge closure -- spanning between Alger Street in Greenfield to Overlook Drive in Schenley Park --  is necessary to accommodate the reconstruction of a new bridge that will be built in the same location. Vehicle traffic will be detoured through the surrounding neighborhoods with the aid of a posted detour. Visit for more information on posted detours.

“The Greenfield Bridge reconstruction is a massive project that has required a tremendous amount of planning and consideration,” said Mayor William Peduto. “It’s very exciting to reach this stage in the process. While this is a necessary investment, we understand that this closure will have a major impact on the surrounding communities and we are committed to working with the community through this process.”

The new bridge is a state-of-the-art steel open-spandrel arch that according to Patrick Hassett, Assistant Director of the Bureau of Transportation and Engineering, "incorporates elements of the existing bridge’s original grandeur by salvaging and incorporating the decorative urns and pylons built in 1921. The new bridge combines a graceful design with improved accommodations for commuters.”

The reconstruction of the bridge includes new bridge abutments, bridge piers, structural steel and new bridge deck consisting of three travel lanes, a bike lane and a sidewalk, with bridge barriers and fencing which will span each side of the new bridge.

Connecting the community of Greenfield to Schenley Park and beyond, a 10-foot pedestrian sidewalk and dedicated bike lane will make the bridge safer for drivers, walkers and bicyclists while expanding the City’s efforts to make Pittsburgh more walkable and bike-friendly. Landscaping of adjacent greenspace and its incorporation as part of Schenley Park will complement the attractiveness of the bridge upon entering and leaving Greenfield.

"When we're on ‘60 Minutes' and people are talking about our crumbling infrastructure, and now you can look at us taking the lead and investing $17 million into revamping our infrastructure," said Councilman Corey O’Connor. “Being able to get through this process is going to be pretty amazing. It actually shows how our city is moving forward."

Pedestrian and Cycling Traffic

Beginning noon on Sunday, October 18, 2015, pedestrian and cycling traffic will be restricted from the bridge. Pedestrians and cyclists can use the Junction Hollow trail via the Alexis Street steps or Saline Street in Greenfield, and Joncaire steps or Joncaire Street in Oakland.  Improvements are being made to these routes to better accommodate pedestrians and cyclists.  

Public Process

The Department of Public Works and Public Safety have established regular meetings to prepare for and respond to traffic conditions resulting from the closure. In addition, CMU’s Mobility Analytic Lab, a division of its Traffic 21 Institute, has developed a regional model for simulating traffic conditions under varying conditions. This model is being used to assess the potential impacts and possible improvements relative to the bridge closure.  

The City and the Oakland Transportation Management Association (OTMA), have established a community outreach website designed to keep the public informed of the Greenfield Bridge construction activities and answer any questions posed by the public.

Port Authority Routes

Port Authority Transit Routes including the 52L Homeville Limited / 53L Homestead Park Limited / 58 Greenfield / 93 Lawrenceville-Oakland-Hazelwood have already been rerouted off the bridge.  For the new bus routes visit

Parkway East (I-376) Restrictions

At various times between now and the late December implosion, travel lane restrictions in either direction will be implemented on the Parkway East, I-376. The traveling public will be notified in advance of these restrictions when they become known.  Between December 26, 2015, to January 3, 2016, I-376 will be closed in each direction for a five day period in order to implode the Greenfield Bridge structure.


The estimated $17.5 million construction project is a City of Pittsburgh project with PennDOT and Federal Highway Administration oversight. The work is being performed by Mosites Heavy Construction Company, a heavy civil highway and bridge contractor.

This closure is expected to be in effect until completion in 2017.


To commemorate the passing of an architectural and community icon, the community has organized the Greenfield Bridge Rock Away the Blues Bridgefest set for this Saturday October 17, 2015 starting at 4 p.m. The Bridgefest is intended to raise awareness of the local businesses impacted by the two year loss of the Greenfield Bridge, a critical artery for the Greenfield community and its markets. In collaboration with the business owners, the event proceeds will be used to promote and support the community and its business districts while the new bridge is under construction.

The lineup includes Joe Grushecky and the Houserockers headlining the evening stage and Pittsburgh’s country rockers NOMaD in the afternoon. I Made It! Market will have a presence as well as a Greenfield businesses, restaurants and local food trucks. The event is family friendly, free, and open to the public. Event details can be found here:
