    Montoursville, PA – A multi-year intersection improvement project continues along the Route 54 corridor near the Route 642 west (Liberty Valley Road) and Route 642 east (Jerseytown Road) intersection in Valley and Mahoning townships, Montour County.

    Traffic Impacts

    Drivers can expect a single lane closure on westbound Route 54. Motorists traveling westbound on Route 54 will not have access to westbound Route 642 (Liberty Valley Rd).  The following detour will be in effect once the closure is implemented:
