53A2 Section Video

SECTION 53A2

Section 53A2 of the Mon/Fayette Expressway (MFE) PA Route 51 to I-376 Project’s southern section begins just north of Coal Valley Road and runs about two miles north of Camp Hollow Road (SR 2043) near Curry Hollow Road in West Mifflin Borough, Allegheny County.

The PA Turnpike Commission awarded Trumbull Corp. the $165.6 million contract in October of 2023. Construction of this section is expected to begin in March 2024 and is scheduled to finish in the summer of 2027.

The contract requires Trumbull Corp. to excavate approximately 3.7 million cubic yards of earth and build five bridges. A full interchange at Camp Hollow Road will also be constructed under the terms of this contract, along with two round-abouts on Camp Hollow Road.

The remaining construction sections will go through the bidding process and begin construction once bids are awarded.


For those who have received mailings related to a proposed noise wall in construction section 53A2, additional information is provided about the noise study and how the PTC conducts noise analysis.
