    I-376 Parkway East High Friction Surface Treatment Work Begins Tuesday in Pittsburgh

    July 03, 2025

    Pittsburgh, PA – PennDOT District 11 is announcing lane restrictions on I-376 (Parkway East) for high friction surface treatment (HFST) work in the City of Pittsburgh, Allegheny County will begin Tuesday, July 8 weather permitting.

    Starting Tuesday, single and double lane restrictions will occur on I-376 as needed weeknights from 9 p.m. to 5 a.m. and weekends from 6 a.m. to noon through late-July in the following locations:

    • Westbound (inbound) I-376 between the Squirrel Hill/Homestead (Exit 74) interchange and Oakland (Exit 73B) Exit
    • Eastbound (outbound) I-376 between the Forbes Avenue/Oakland (Exit 72A) and the Squirrel Hill/Homestead (Exit 74) interchange

    Crews from RAM Construction Services will conduct the work.

    HFST is an innovative technique to improve the safety of motorists at high-priority crash locations throughout the commonwealth. Road surfaces become polished in areas where drivers brake often, like going around curves, down steep roads, or at an intersection. This makes vehicles skid more because there is less friction between the tires and the road surface. Wet road surfaces can also reduce pavement friction and cause skidding or hydroplaning.

    HFST is added to the top of a road surface, using materials, such as bauxite, to create more friction on pavement. These materials, called aggregates, are high quality and are less likely to wear down than normal pavement. Having greater friction helps to keep vehicles in their lane on slippery pavement around curves and helps the driver to stop.

    Please use caution if traveling on this roadway. Work zone safety is everyone’s responsibility.
