Interstate 70 Matthew Smelser Memorial Bridge Single-Lane Restrictions Begin Monday in Westmoreland County


Uniontown, PA – Pennsylvania Department of Transportation (PennDOT) District 12 is announcing a short-term single-lane restriction of westbound Interstate 70 on the Matthew Smelser Memorial in Rostraver Township, Westmoreland County.

The single-lane restriction will be in place between Exit 49 (Smithton) and Exits 46B/46A (Route 51) and is scheduled from 9:00 AM on Monday, October 2 to 5:00 AM on Tuesday, October 3 depending on weather and operations.

Crews from Golden Triangle Construction Company will be removing barrier and the single-lane closure of the eastbound travel lane.

Motorists are asked to be alert, turn on headlights, and exercise caution while driving through the work zone. Safety is everyone's responsibility. 

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 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 Twitter alerts
