PennDOT District 11 is announcing overnight High Friction Surface Treatment (HFST) operations in various locations in the Municipality of Penn Hills, Allegheny County will begin Monday, September 13 weather permitting.

Beginning Monday, crews will conduct HFST operations, requiring single-lane closures nightly from 8 p.m. to 6 a.m. through Friday, September 24 at the following intersections in the Municipality of Penn Hills:

  • Route 130 (Allegheny River Boulevard) at Sandy Creek Road
  • Route 130 (Allegheny River Boulevard) at Nadine Road

Additionally, HFST operations, requiring single-lane closures in the Municipality of Penn Hills will occur nightly starting Monday, September 20 through Friday, October 1 according to the following schedule:

  • Route 400/Route 380 (Franstown Road) at Route 791 (Rodi Road) from 8 p.m. to 6 a.m.
  • Route 400/Route 380 (Franstown Road) at Route 2064 (Lime Hollow Road) from 9 p.m. to 6 a.m.

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.

Crews from Mekis Construction will conduct the work, with flaggers assisting motorists through the intersections.
