​Westbound Interstate 70 and Southbound Route 51 Single-Lane Restrictions Tomorrow in Westmoreland County


Uniontown, PA – Pennsylvania Department of Transportation (PennDOT) District 12 has announced that single-lane restrictions are scheduled tomorrow, Thursday, October 19, from 8:00 AM until 3:00 PM in Rostraver Township, Westmoreland County on:

  • Westbound Interstate 70
    • Between Exit 49 (Smithton) and Exits 46A/46B (Route 51)
  • Southbound Route 51
    • Between Concord Lane and Finley Road 

Crews from Golden Triangle Construction Company will be removing overhead cantilever signs.

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

This work is part of a $120.6 million 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 project includes one mile of reconstruction and widening on Route 51 which involves several intersecting roadways and the relocation of Finley Road and Route 981. Golden Triangle Construction Company was awarded the bid and the project is anticipated to be complete in October 2027.
