Pittsburgh, PA – PennDOT District 11 is
announcing overnight High Friction Surface Treatment (HFST) operations on
various roads in Allegheny County will continue Monday night, July 31 weather
permitting.
Beginning Monday
evening, crews will conduct HFST operations, requiring single-lane closures
weeknights from 7 p.m. to 6 a.m. through Friday, August 25 in the following
locations:
Route 30 (Lincoln Highway) at
Clyde Avenue in North Versailles Township
Route 65 (Ohio River Boulevard)
between Shilow Avenue to Elizabeth Avenue in Bellevue Borough
Route 3038 (Gilkeson Road)
between Cedar Road and Old Gilkeson Road in the Municipality of Mt.
Lebanon
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 the
Truesdell Corporation will conduct the work.
