Interstate 70 Barrier Resetting Overnight Friday in Westmoreland County

​Uniontown, PA-Pennsylvania Department of Transportation (PennDOT) District 12 is announcing an overnight single-lane restriction on Interstate 70 West from Friday, October 4, 8:00 PM, to Saturday, October 5, 6:00 AM, between Exits 46A/46B (Route 51) and Exit 44 (Arnold City) in Rostraver Township, Westmoreland County.

Crews from Golden Triangle Construction will remove and reset barriers to accommodate new phases of traffic control. All work depends on weather and operations.

This is part of the $120.7M infrastructure investment for the widening and reconstruction of Interstate 70 at the Route 51 Interchange (Exit 46). Crews from Golden Triangle Construction are replacing the current with a Diverging Diamond Interchange (DDI). It includes full-depth roadway reconstruction, updated drainage, updated lighting and traffic signals, and completion of the westernmost structure carrying Route 51 over I-70.

One mile of Route 51 is being reconstructed and widened to accommodate the new interchange, as well as several intersecting roadways, including the relocation of Finley Road and Route 981. The project is anticipated to be completed in October 2027.

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