    Interstate 79/Route 910 Wexford Interchange Phase Change Begins Next Week in Allegheny County

    New traffic pattern to be implemented on Wexford Bayne Road (Route 4042) by Wednesday

    April 10, 2026

    Pittsburgh, PA – The Pennsylvania Department of Transportation (PennDOT) is announcing the next phase of work for the Interstate 79/Route 910 Wexford Interchange project in Franklin Park Borough and Marshall Township, Allegheny County will begin Tuesday, April 14 weather permitting.

    Beginning at 7:00 AM Tuesday morning, there will be single-lane restrictions controlled by flaggers in both directions of Wexford Bayne Road (Route 4042) between the I-79 interchange and the Nicholson Road (Route 4049) intersection. These restrictions will be in place around-the-clock through 3:00 PM Wednesday, April 15 to allow crews to relocate signal heads and conduct line painting operations.  The restrictions could be lifted earlier if the work is completed sooner.

    When the signal head and line painting operations are completed, the new traffic configuration between the I-79 interchange and Nicholson Road will be as follows through late May:

    Eastbound Wexford Bayne Road

    • One thru-lane of traffic will be maintained heading eastbound to Route 910
    • The second thru-lane will be closed
    • The right-hand turn lane to southbound I-79 will remain open

    Westbound Wexford Bayne Road

    • Westbound traffic will be shifted

    Sunny Hill Drive

    • Traffic exiting Sunny Hill Drive will be prohibited from making left-turns onto Wexford Bayne Road
    • Eastbound traffic on Wexford Bayne Road will be prohibited from making left-turns onto Sunny Hill Drive
    • These modifications at the Sunny Hill Drive intersection will be permanent

    Additionally, there will be intermittent westbound Wexford Bayne Road turning lane restrictions at the Nicholson Road intersection from 9:00 AM to 3:00 PM weekdays through late May for median removal and replacement work. Flaggers will assist motorists through the intersection.

    Please stay alert and drive cautiously – safety is everyone’s responsibility.

    The $46.5 million I-79/Route 910 Wexford Interchange project will include new construction of a full offset single-point urban interchange (SPUI) at the I-79/Route 910 Wexford Interchange. The project limits along I-79 are from approximately 1.5 miles north of the I-79/I-279 split to Mingo Road and the limits on Route 910 are between Nicholson Road and Brandt School Road/VIP Drive in Franklin Park Borough and Marshall Township. Bridge work includes two new flyover structures over I-79, as well as sign structures and bridge preservation to the existing bridge carrying Route 910 over I-79. Other work includes traffic signal improvements, new highway lighting, minor ITS upgrades, drainage work, signing/pavement marking and guide rail updates, and other miscellaneous construction. During construction, three lanes of traffic in each direction are expected during peak travel times, as well as temporary ramps to maintain access for most of the project. Additionally, short-term lane and shoulder closures will be utilized. Beams for the new structures will be set during overnight traffic stoppages on I-79 northbound, while I-79 southbound will be detoured overnight using the existing southbound off and on-ramps during beam setting. The project is anticipated to continue through the 2027 construction season.
