Single-lane restrictions are scheduled to begin Monday for PennDOT road projects in Greensburg and Rostraver.

Westbound traffic will be restricted to a single lane on Route 136, between Hamilton and Lincoln avenues, during work on the bridge over Route 30 in Greensburg. The work, expected to continue through early May, is part of a $1.3 million bridge preservation project by contractor Mekis Construction Corporation.

In Rostraver, lane restrictions are slated on Route 906 (Webster Road) between C. Vance DeiCas Memorial Highway/Donora-Monessen Bridge and the Allegheny County line. The restrictions will be in place from 7 a.m. to 5 p.m. weekdays, through late April, as Tresco Paving Corporation mills and resurfaces the road.
