The Mon/Fayette PA Route 51 to I-376 Project has gone through an exhaustive analysis and review process that began more than two decades ago.
The Environmental Impact Statement (EIS) for the project was approved in December 2004 by the Federal Highway Administration identifying the selected alternative to be designed and constructed. While the design phase began in 2005, it was halted
in 2009 due to lack of funding.
In 2013, Act 89 was enacted and provided the necessary funding to allow the project to restart.
In 2015, the Pennsylvania Turnpike Commission (PTC) performed studies to identify how the originally designed project could be modified and completed with the funding available through Act 89.
Studies showed eliminating the west leg of the original project that led into Pittsburgh would substantially reduce the project cost, as well as residential and business displacements. This updated information was added to the EIS, which was approved in 2019, and reduced the scope of the original project.
A re-evaluation of the approved FEIS will be completed once design work starts north of the Monongahela River.
Click here to see drone footage of the path that the Mon/Fayette Expressway is expected to take in the southern section which stretches from PA Route 51 Jefferson Hills Borough to PA route 837 in Duquesne, Allegheny County.
This video was taken prior to construction. Footage near the Allegheny County Airport is not included due to flight restrictions near the airport.
To help you better understand the design process, detailed design maps and presentations have been archived below and are available for review.
Virtual Presentation for Dravosburg/West Mifflin Design Modifications
The Pennsylvania Turnpike Commission invites you to view a special presentation concerning design modifications to the PA Route 51 to I-376 Mon/Fayette Expressway Project being considered in the area of West Mifflin and Dravosburg – specifically between Camp Hollow Road and Pittsburgh-McKeesport Boulevard.
The design modifications in this area are due to recent findings from geotechnical explorations (drilling), utility relocation issues, ongoing assessment of environmental impacts and future maintenance considerations.

August 2016 Public Meeting Graphics and Maps
Thank you to the hundreds of people who attended our August 2016 public meetings. Your feedback and questions were greatly appreciated. Please feel free to download the displays or view the project maps shown at those meetings, which are listed below. More public meetings are being planned for 2018 once PA Turnpike engineers finish the timeline for this project.
The Mapping Boards below illustrate the Mon Fayette Expressway alignment. This table provides a key to the Mapping Board that provides details for each municipality. Please note that although the map files have been compressed as much as possible, some are large so make take time to download.
