    Route 978 Millers Run Road Bridge Replacement Starts Tuesday in South Fayette Township

    March 19, 2025

    Pittsburgh, PA – PennDOT District 11 is announcing replacement work on the Millers Run Road (Route 978) structure over Dolphin Run in South Fayette Township, Allegheny County will begin Tuesday, March 25 weather permitting.

    Beginning at approximately 7 a.m. Tuesday, bridge replacement work will begin on Millers Run Road between Mohawk Road and Battle Ridge Road (Route 978). To allow this work to occur, Millers Run Road will close at the bridge location continuously through mid-August. All traffic will be detoured.  

    Posted Detour

    • West of the Bridge
    • Follow Millers Run Road (Route 978) westbound to Route 50
    • Turn left onto Route 50

    An inspection of the bridge found advanced deterioration in late 2022 and was immediately closed to traffic until a temporary structure could be installed in early 2023.  Additional work on this $1.9 million bridge replacement project will include milling and paving of the approach roadway, drainage improvements, guide rail updates, and pavement marking installation. The project is expected to conclude in the spring of 2026.
