Anticipated Schedule
Early 2019 to Mid-2022

Travel Details
I-79 northbound and southbound continue to progress through various stages of construction phasing and is currently an active work zone with a 45 MPH speed limit. Northbound traffic is nearing it's final configuration with work ongoing in the median at the north and south ends of the project. Southbound traffic is currently using a split lane configuration at the south end of the project to complete permanent paving on the interior lanes. Rest areas both northbound and southbound are open. 

SR 576 is now open to traffic through the project with access being provided on a ramp from I-79 northbound to 576 westbound toward the airport, and traffic from 576 eastbound can merge onto I-79 southbound near the National Cemetery of the Alleghenies.

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.
