    Project Overview

    County: Cumberland and Dauphin
    Municipality: Lemoyne Borough and Harrisburg City
    State Route: 0083-094
    Local Name: Interstate 83, John Harris Memorial Bridge, South Bridge
    Project Type: Bridge Replacement and Interchange Improvement
    MPMS Number: 113754
    Proposed Construction Start: 2026
    Last Updated: September 2025

    The I-83 John Harris Memorial (South) Bridge Project is currently in the final design phase in preparation for procurement and construction. Construction is anticipated to begin in 2026. 

    The I-83 John Harris Memorial (South) Bridge was built in 1960, and widened in 1982, and connects downtown Harrisburg to its neighboring communities to the west in Cumberland County. The bridge currently carries more than 125,000 vehicles over the Susquehanna River every day.

    The South Bridge is nearing the end of its serviceable lifespan, which means that wear and tear requires more regular, frequent, and costly repairs. In addition to the replacement of the bridge, the Lemoyne interchange will be reconfigured, the S. 3rd Street bridge in Lemoyne will be replaced, and the viaduct from the Susquehanna River to Cameron Street including the Front Street/2nd Street interchange will be reconstructed. The purpose of the I-83 South Bridge Project is to improve traffic flow and safety around the Harrisburg metro region. 

    The Federal Highway Administration (FHWA) issued a Finding of No Significant Impact (FONSI) for the Pennsylvania Department of Transportation’s (PennDOT) I-83 South Bridge Project. An Environmental Assessment (EA) was prepared for the project and shared with the public for review and comment from October 17 through November 16, 2023. All comments received during the public comment period received equal consideration and are addressed in the FONSI document, which can be seen here​. The EA, which was prepared in accordance with the National Environmental Policy Act, examined the potential impacts to natural, social, economic, and cultural resources from this project and alternatives under consideration.
