    Southbound Route 51 Clairton Boulevard Patching Saturday in Jefferson Hills

    October 31, 2025

    Pittsburgh, PA – The Pennsylvania Department of Transportation (PennDOT) is announcing a lane restriction on southbound Route 51 (Clairton Boulevard) in Jefferson Hills Borough, Allegheny County will occur Saturday, November 1 weather permitting.

    A single-lane restriction will occur on southbound Route 51 at the intersection with Coal Valley Road from 9:00 AM to 3:00 PM Saturday. Crews from Lindy Paving will conduct patching and roadway adjustment work.  

    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.
