Construction Details

SECTION 53A1

Section 53A1 of the Mon/Fayette Expressway (MFE) PA Route 51 to I-376 Project’s southern section begins where the current MFE ends at PA Route 51 in Jefferson Hills Borough and stretches approximately three miles north of Coal Valley Road.

Construction of this section started in March 2023 and is expected to be finished in fall of 2026. The nearly $214 million contract requires Trumbull Corp. to excavate more than four million cubic yards of earth and build six bridges. Five of the bridges will be built as part of the mainline Mon/Fayette Expressway while the sixth will carry PA Route 885 over the Mon/Fayette Expressway. A cashless toll point will also be built within this section.

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