    Project Overview

    County: Allegheny
    Municipality: City of Pittsburgh
    State Route: Interstate 376
    Local Name: I-376
    Project Type: Drainage Improvement
    MPMS Number: 112249
    Proposed Construction Start: October 2026
    Proposed Construction End: Fall 2027
    Last Updated: 09/25/2026

    This $14.34 million project along westbound I-376 (Parkway East) within the City of Pittsburgh will include work to reconstruct and raise 1,150 feet of existing floodwall to reduce the frequency of flooding events between the Grant Street (Exit 71A) interchange and the Fort Pitt Bridge. Work includes the installation of micropiles to strengthen the existing structural foundation under the roadway, full pavement replacement, and repairing and upgrading the existing pump and piping systems. A long-term single-lane restriction and ramp closures, as well as Mon Wharf parking area impacts, will be in place for majority of the project with possible weekend closures and lane restrictions. During the 2027 construction season, travelers can expect a 12-day full closure and detour of westbound I-376 for full-width concrete pavement reconstruction. The overall project is expected to conclude in the fall of 2027. Golden Triangle Construction Company is the prime contractor.

    The “bathtub” area of the Parkway East, lies between the Monongahela River and downtown Pittsburgh. This segment of the three-lane highway (two through lanes and one auxiliary exit lane) is roughly 5 feet higher than the normal river stage of 16 feet and is currently protected by a variable height floodwall with a minimum height of approximately 4 feet at the sump pump locations. The "bathtub" has experienced increased closures due to flooding over the past decade. Each closure diverts approximately 43,000 vehicles and costs a significant amount of money and time to allow crews to conduct clean-up activities once the river recedes, which includes pumping the water and cleaning out mud and debris from the area in order to reopen the road. This project aims to reduce the frequency of flooding events and improve maintenance response time afterwards.
