Interstate 70 Lane Restrictions Next Week in Westmoreland County


Uniontown, PA – Pennsylvania Department of Transportation (PennDOT) District 12 is announcing that single-lane restrictions on Interstate 70 are scheduled to begin Tuesday, June 18, between Exit 46A/46B (Route 51) and Exit 49 (Smithton) in Rostraver Township, Westmoreland County.

Crews from Geronimo Painting will be working on containment for the Matthew Smelser Memorial Bridge over the Youghiogheny River.

Daytime restrictions – eastbound and westbound – are anticipated from Tuesday, June 18 to Thursday, June 20, depending on weather and operations.

This work is part of the $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.

Remain alert and follow the posted signs and speed limits. Safety is everyone's responsibility.

Motorists can check conditions on major roadways by visiting 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. 511PA is also available through a smartphone application for iPhone and Android devices, by calling 5-1-1, or by following regional X alerts.
