South Oakland

Swinburne Bridge

About

The City of Pittsburgh, in cooperation with the Federal Highway Administration (FHWA) and Pennsylvania Department of Transportation (PennDOT), is advancing the Swinburne Bridge replacement project.

The bridge functions as a critical link between Four Mile Run, South Oakland, Greenfield, Hazelwood, and downtown. It weaves beneath the I-376 Frazier St Viaduct and over CSX/Allegheny Valley railroad, Saline St, serving as a gateway to Four Mile Run.

The current Swinburne bridge, built in 1915, consists of six deck- and thru-girder spans on steel bent towers. While novel for its day, it lacks modern principles of bridge design which provide increased redundancy and decreases future maintenance needs.

 

Upcoming

The June 16 public meeting has been rescheduled for July 14 at 6:30 PM. At this time, the design team is ready to share preliminary details with the community about the proposed bridge and the construction process.

Past Updates

To allow for improved response time and attendance at the first public meeting, the Zoom meeting previously scheduled for June 16 at 6:30 PM was postponed.

Preliminary engineering is currently underway on the design of a complete reconstruction of the bridge. Preliminary engineering focuses on mapping out and defining the scope of the project as well as the early design of how to take the project from A-to-Z. The design team has been focusing on how to minimize impacts to those who rely on crossing the bridge daily or live and work in the vicinity, as well as how to improve usability for future generations of Pittsburghers.

Second Avenue Multimodal Corridor Study

Developer: Southwestern Pennsylvania Commission (SPC)

Project summary: The City of Pittsburgh, Allegheny County, and Port Authority invited SPC to conduct a study to identify people's transit needs along Second Ave. The scope of this study includes Second Ave from the 10th St. Bridge to the Glenwood Bridge and Bates from Second up to the Boulevard. One component of the study will identify ways to improve transit connections for South Oakland residents with an emphasis on reducing the car-flow of single occupancy vehicles into Oakland and encouraging an overall mode shift to more efficient transit options. SPC held a public meeting on Feb 19th to solicit feedback from residents. A second public meeting took place on May 8th. The final public meeting took place on Thursday, July 25, 2019. Residents were also able to provide comments online.

The final report is available here (section 4 outlines the final plan).
