Residents and commuters in Jefferson Hills are bracing for another closure of Coal Valley Road, a move that's set to shake up local traffic patterns for approximately two months. WPXI reported that the closure, starting today, is due to reconstruction efforts tied to the Mon-Fayette Expressway project. The stretch between state routes 837 and 885 will be out of commission, with a nearly four-mile detour slated to redirect traffic.

Drivers who frequently pass through the area will need to adapt to route changes, such as taking Route 885 and Walnut Avenue through Clairton to reconnect with Route. 837 near the Clairton-Glassport Bridge, according to information from CBS News Pittsburgh. It's a 1.7-mile closure, but the detour will add extra miles and potentially increase the time required for regular commutes.

This isn't the first time that Coal Valley Road has seen closures due to construction work. Over the past few years, the ongoing expressway project has necessitated several closures, as the Pennsylvania Turnpike Commission works to connect Pennsylvania 43 to Interstate 376 in Monroeville. The construction work includes rebuilding the road surfaces around the newly constructed bridges.

The estimated timeline provided suggests a reopening in early August; however, much of this schedule is contingent on cooperative weather conditions.
