PennDOT District 11 is announcing the implementation of a long-term crossover on Route 51 (Clairton Boulevard) in Pleasant Hills and Jefferson Hills boroughs, Allegheny County will begin Friday night, March 28 weather permitting.
A traffic crossover will be implemented on Route 51 between Coal Valley Road and East Bruceton Street beginning at 8 p.m. Friday, March 28. 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 Clairton Boulevard 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.
