Long-Term Traffic Restrictions On Way For Route 51

PITTSBURGH, PA — Traffic on Route 51 in Pleasant Hills and Jefferson Hills will be reduced to one lane in each direction for a lengthy period beginning Friday, PennDOT announced.

A traffic crossover will be implemented on Route 51 between Coal Valley Road and East Bruceton Street beginning at 8 p.m. Friday. Southbound traffic will be crossed over into the northbound lanes
around-the-clock through mid-June during this first phase of roadway reconstruction work.

A single lane of traffic in each direction will be maintained in the northbound lanes. Northbound traffic will only be able to turn left at signalized intersections. The crossover is expected to
be fully in place by late Saturday evening.

This $19.85 million roadway project on Route 51 includes milling and resurfacing, concrete replacement, bridge preservation work on three structures (two structures over Lewis Run and one structure over Lebanon Church Road), drainage work, guide rail improvements, ADA curb ramp updates, PRT bus stop improvements, signing and pavement marking installation, and other miscellaneous construction activities.

Also included is an adaptive traffic signal project that will provide upgrades to 24 intersections, including full signal replacement at nine intersections, from Peters Creek Road in Jefferson Hills Borough to Stewart Avenue in the City of Pittsburgh.

Up to one-mile-long single-lane restrictions will occur in each direction limiting left-turn
movements except for at signalized intersections. Detours for the left-turn movements will be posted. The project is anticipated to conclude in late 2026.
