Construction on the Swinburne Bridge is scheduled to begin after rehabilitation of the Charles Anderson Bridge is complete.

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. 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.

At this time the design team is ready to share preliminary details with the community about the proposed bridge and the construction process. Please check out the presentation from our 7/14/2022 public meeting in the document library, below!

While the engineering will take a couple more years, we aim to provide updates on our progress, what you can expect during construction, and what to look forward to once it's complete. Questions, comments, and feedback can be submitted at the bottom of this page.

A huge thanks to everyone who participated in our first public meeting, held on July 14, 2022! The design team is compiling notes from the meeting and look forward to evaluating how to provide the best possible bridge to meet the needs of the surrounding communities.
