Route 51 lane restrictions to begin Monday in Robinson Township

Commuters relying on Route 51 to get where they’re going likely will need to add more time to the drive starting Monday, weather permitting.

Single-lane restrictions will be in place in both directions on Route 51 between the northbound and southbound on-ramps at the I-79 Coraopolis/McKees Rocks interchange from 7 a.m. to 4 p.m. Monday. Crews will remove guiderail and install barrier along the shoulder to support structure work on I-79, PennDOT said.

The shoulders between the northbound and southbound on-ramps at the I-79 Coraopolis/McKees Rocks interchange will remain closed around-the-clock in each direction through mid-November.

The work is part of the $43.9 million I-79 “S-bend” project that includes pavement reconstruction and bridge preservation work on five main roads (I-79 north and south over Clever Road, I-79 north and south over Route 51, and the Neville Island Bridge).

There also will be milling and paving of three ramps at the Route 51 (Coraopolis/McKees Rocks) interchange. The project includes guiderail replacement, highway lighting, new pavement markings and other miscellaneous construction work.
