    Uniontown, PA - Pennsylvania Department of Transportation (PennDOT) District 12 is announcing that single-lane restrictions are scheduled to occur on Interstate 70 between Exit 44 (Arnold City) and Exit 49 (Smithton) in Rostraver Township, Westmoreland County.

    Single-lane restrictions:

    • Wednesday, February 25
