Uniontown, PA – Pennsylvania Department of Transportation (PennDOT) District 12 is announcing daytime single-lane restrictions on eastbound and westbound Interstate 70 in Rostraver Township, Westmoreland County.

Restrictions will be in place between Exit 49 (Smithton) and Exits 46B/46A (Route 51) and are scheduled from Monday, October 9 until Thursday, October 12, 9:00 AM to 3:00 PM each day, depending on weather and operations.

Crews from Golden Triangle will be applying concrete protective coating sealer to portions of the new concrete roadway weather permitting.

This work is part of a $120.6 million Interstate 70 Project involving the widening and reconstruction of Interstate 70 along with the reconstruction of the Route 51 Interchange (Exit 46) to replace it with a Diverging Diamond Interchange (DDI). To accommodate the new interchange, the plans include one mile of reconstruction and widening on Route 51, and several intersecting roadways including the relocation of Finley Road and Route 981. The project is anticipated to be complete in October 2027.

Motorists can check conditions on major roadways by visiting www.511PA.com. 511PA, which is free and available 24 hours a day, provides traffic delay warnings, weather forecasts, traffic speed information and access to more than 1,000 traffic cameras.
