SR980 map

The PA Turnpike Commission (PTC) has awarded a $3 million contract to Plum Contracting, Inc., based in the Pittsburgh region, for the drainage work to be performed along State Route 980 in McDonald Borough, Washington County.

The contract calls for Plum Contracting to perform the work necessary to construct drainage improvements and perform channel restoration and stabilization along a tributary that flows into Robinson Run. The work will include but not be limited to replacing and correctly installing drainage pipe with up-to-code materials, restoring the open channel, coordinating with utility companies, as well as repaving the roadway.

The work is scheduled to begin in September 2022 and will include daylight operations. The contractor tentatively will work four, ten-hour shifts, Monday through Thursday, but may work additional hours if needed.

This work schedule is subject to change based on the weather conditions, but the project is expected to be finished by fall of 2023.

55W Wetland Mitigation Site

Wetlands 55W Wetland Mitigation Site was completed by the contractor, Cast and Baker Corporation on December 6, 2016. The site is located approximately 3/4 of a mile northeast of Burgettstown PA, adjacent to State Route 4012, and west of Raccoon Creek in Washington County, PA. As a result of the construction of the Southern Beltway, 9 acres of new wetland has been constructed adjacent to an existing wetland.

The project involved the removal of approximately fifty thousand cubic yards of material, replaced with approximately nine thousand cubic yards of topsoil for wetland infiltration; reseeded and planted with specific vegetation/shrub plants that are designed to thrive in a wetland area.

The Wetland Mitigation Site area is adjacent to an existing wetland north of the site and is also adjacent to PA State Game Lands. The 55W mitigation project is in keeping with the PA Turnpike's commitment to utilizing Best Management Practices.

Section I-376 to U.S. Route 22

Completed October 2006

The Southern Beltway I-376 to U.S. Route 22 Project, also known as the Findlay Connector, was the first to be constructed and opened to traffic in October 2006. This project begins at the existing Pittsburgh International Airport Midfield Terminal Interchange on I-376. It then proceeds southward 6 miles to a new interchange with U.S. Route 22 between the existing Bavington and PA Route 980 interchanges. This project received environmental clearance, the Record of Decision, in May 1998. The total project cost was $238 million.

CASHLESS TOLLING CONVERSION
(Completed Summer 2018)

This project converted the Findlay Connector (Toll 576) to all electronic tolling by constructing overhead gantries outfitted with E-ZPass Scanners and high speed cameras. The cashless tolling plaza is located at Milepost S-2.60, approximately 1.1 miles west of the Westport Road Interchange, Exit 4. The former toll plazas at Exit 2 (U.S. Route 30), Exit 4 (Westport Road), and Exit 6 (U.S. Route 22) have been demolished. This work is part of the PA Turnpike’s transition to Cashless Tolling. Visit www.nocashzone.com for additional information about the Findlay Connector conversion and the overall Cashless Tolling Project.

Mon/Fayette Expressway and Southern Beltway Project Map

    I-79 to Mon/Fayette Expressway

    This project begins with the interchange at I-79 near the Allegheny/Washington County line and proceeds approximately 12.5 miles eastward to a new interchange with the Mon/Fayette Expressway near Finleyville. The U.S. Army Corps of Engineers (USACE) issued a Record of Decision in May 2009. The Selected Alternative begins at Morganza Road at the proposed interchange to I-79 and continues in a south/southeasterly direction through Cecil, Peters, North Strabane, Nottingham and Union townships to a new interchange with Turnpike 43 south of Finleyville. The PTC will proceed with final design, right-of-way acquisition and construction of the project as funding becomes available.
