    Northbound Route 51 Clairton Boulevard Patching Operations Saturday in Pleasant Hills

    October 21, 2026

    Pittsburgh, PA – The Pennsylvania Department of Transportation (PennDOT) is announcing patching operations on northbound Route 51 (Clairton Boulevard) in Pleasant Hills Borough, Allegheny County will occur Saturday, October 24 weather permitting.

    There will be a single-lane restriction on northbound Route 51 from Lewis Run Road continuing approximately one-half mile north from 7:00 AM to 6:00 PM Saturday. Crews will conduct patching operations. The restrictions could be lifted earlier if the work is completed sooner.

    Please allow extra time and use caution if traveling on this roadway. Work zone safety is everyone’s responsibility.

    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 2028.
