I-79 Widening, Bridges and Bridgeville Interchange Reconfiguration

In July 2022, the General Assembly amended the state's P3 law to remove tolling as a means of funding the MBP3. As a result, the path forward for the I-79 Bridgeville Widening, Bridges and Bridgeville Interchange Project is still being evaluated.


Project Description

The I-79 Widening, Bridges and Bridgeville Interchange project will replace the northbound and southbound bridges on I-79 mainline over SR-50, which were built in 1965 and last rehabilitated in 1998. The project also includes widening I-79 from two to three lanes in each direction and extending from Alpine Road north beyond SR-50 and Chartiers Creek to just before the Collier interchange and Prestley Road in Bridgeville, Allegheny County. The I-79 corridor carries an average of 87,000 vehicles daily, approximately 12 percent of which is truck traffic.

The purpose of the I-79 Widening, Bridges and Bridgeville Interchange project is to provide a safe and reliable crossing of I-79 over SR-50 and to widen I-79 to enhance capacity. In addition to replacing the dual I-79 bridges over SR-50, the W&LE Railroad and Chartiers Creek, the project will make improvements to the I-79/SR-50 interchange and bring the roadway up to date in order to improve safety along the corridor.

September 2022 Project Update

In February of 2021, the project was selected as a candidate for bridge tolling under the Major Bridge P3 (MBP3) Initiative and analysis was being performed to study the potential impacts related to tolling and toll diversion in accordance with the National Environmental Protection Act (NEPA).  In July 2022, the General Assembly amended the state's P3 law to remove tolling as a means of funding the MBP3 and PennDOT is continuing to evaluate the path forward for the I-79 Bridgeville Widening, Bridges and Bridgeville Interchange Project.
