In The Run

Swinburne Bridge Replacement Project

Project Background

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 6/16/2022 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.

  • Project costs and funding

For more information or to ask a question, please visit

About the Project:

Four Mile Run encompasses Schenley Park and several Pittsburgh neighborhoods including Greenfield, Hazelwood, Oakland, Squirrel Hill, and the Run. These neighborhoods and the park are located within the M-29 sewershed where all of the sewers flow to the same outfall, the 29th along the Monongahela River.

To help to reduce combined sewer overflows, basement backups, and neighborhood flooding, the Four Mile Run Stormwater Project will capture and route stormwater through a natural channel that will follow the path of the historic streams that formed Four Mile Run from Panther Hollow Lake to the Monongahela River.

Regarding the June 25th Playground Incident

By now many people have seen the video of the altercation that took place on June 25th at the 4 Mile Run playground. Some online and print publications have mistakenly reported that one of the participants, Thomas D’Andrea, is a committee member in the Greenfield Community Association. This is not true. He is not and has never been a member of our Board or involved in any of our committees. He has no affiliation with the Greenfield Community Association that we are aware of other than being a resident of the neighborhood.

The GCA is a community based volunteer organization whose mission is to fund, support, develop and enhance the community. We, as a community organization, withhold expressing opinions on behalf of the entire community unless there is a clear, understanding of the facts and call for a GCA position. When incidences like this occur within our neighborhood we fully respect and cooperate with the appropriate authorities involved. When all the facts are known and the relevant judicious processes complete, the GCA serves as a conduit for communicating the findings and a forum for their discussion. In the meantime we advocate for civility, accuracy, and respect for the law, and a constructive community dialogue. Accordingly, GCA will be turning off the comment feed on its facebook page and hiding existing comments that are misinformed or offensive. The board feels social media is not the appropriate nor constructive media for advancing a fuller more accurate understanding of the event and its consequences.

Our goal is to constantly strive to make Greenfield a better place for all the residents and business owners. A constructive and informed dialogue is key to the continued success and well being of our neighborhood.

We thank the publications we have contacted for making the appropriate corrections to their stories.

— The Greenfield Community Association Board of Directors

GCA volunteers help clean up in The Run, 14 April 2018


The weather was great last Saturday when volunteers helped outdoors at the annual GCA Spring Cleanup on April 14, 2018.

The cleanup focused on three areas:  The Run, Magee Field, and the garden at Ronald Street.  Here are David Cashmere’s photos from our very busy day.

Above, all ages participated in The Run.  Below, the Magee Field cleanup crew pauses for a photo.

DESCRIPTION from Department of Mobility and Infrastructure (DOMI)

Thanks to everyone who attended the public meeting on January 18th, 2018. Please join us for the next public meeting to continue the conversation about a potential connection between Hazelwood, Greenfield, Four Mile Run, and Oakland:

February 20th, 2018
5-8 PM
Pittsburgh Firefighters Local 1, 120 Flowers Avenue, Pittsburgh, PA 15207

At the last public meeting, we presented five alternative routes for this connection, and what the modes of transit might be. Since then, we have been reviewing your feedback on the alternatives, the priorities that were expressed by each of the neighborhood groups, siting constraints, and the technical aspects of developing an effective connection. We have developed a preferred alternative for consideration that attempts to address the concerns we heard, along with the operational constraints of providing an efficient connection.

Please join us on Tuesday, Feb. 20th to hear about the preferred alternative and continue the discussion about the potential modes of transit along the route. The evening will include an open house for the first hour, a presentation regarding specific elements of the potential route, and an opportunity to provide feedback in small groups.

Register for the meeting on February 20th at 5 PM at Pittsburgh Firefighters Local here.

After the meeting, the presentation will be posted to, where you will be able to view it and comment on it (the presentation from the January 18th meeting is also posted on the website).

We welcome your comments there, or you can always email them to us at

Survey Results From The Run, November 2017


In the Summer & Fall of 2017 the Greenfield Community Association
worked with residents of Four Mile Run to conduct a comprehensive,
154-question community survey. The Run Community Census gathered information on topics of importance to participants,
members of their household, and the neighborhood.

The Census is done and the results were presented to the community a few weeks ago. Here are three documents from the survey:
