    Interstate 79 Wexford Interchange Overnight Restrictions Next Week in Allegheny County

    Interstate 79 to be reduced to a single-lane of traffic, daylight shoulder restrictions extended

    October 16, 2025

    Pittsburgh, PA – The Pennsylvania Department of Transportation (PennDOT) is announcing overnight restrictions on Interstate 79 and the Wexford Interchange ramps in Franklin Park Borough and Marshall Township, Allegheny County will begin Monday night, October 20 weather permitting.

    Nightly restrictions will occur according to the following schedule:

    Monday through Wednesday, October 20-22

    • Southbound I-79 will be reduced to a single-lane of traffic from Mingo Road to approximately 1.5 miles north of the I-79/I-279 split
    • 7:00 PM to 6:00 AM each night

    Thursday and Friday, October 23-24

    • Northbound I-79 will be reduced to a single-lane of traffic from just north of the I-79/I-279 split to Mingo Road
    • Thursday, October 23 from 7:00 PM to 6:00 AM
    • Friday, October 24 from 7:00 PM to 9:00 AM

    Crews from Golden Triangle Construction Company will conduct paving of the temporary northbound Interstate 79 off-ramp to Route 910/Wexford Bayne Road and access roads within the median, complete joint repair work, and barrier installation.

    Ramp traffic will be shifted onto the shoulders, as needed, at the on and off-ramps at the I-79 Wexford Interchange to accommodate the above work. 

    Additionally, crews will start driving piles within the median near the southbound I-79 off-ramp to Route 910/Wexford Bayne Road during daylight hours.

    Also, weekday shoulder restrictions from 9:00 AM to 3:00 PM have been extended through late October in the following locations:

    • I-79, in both directions, between approximately 1.5 miles north of the I-79/I-279 split and Mingo Road
    • Northbound and southbound I-79 interchange on and off-ramps at Route 910/Wexford (Exit 73)

    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 Drive and Brandt School Road/VIP 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.
