    Project Overview

    County: Erie
    Municipality: City of Erie
    State Route: 0079
    Local Name: Interstate 79
    Project Type: Bridge Rehabilitation
    Proposed Construction Start: 2026
    Proposed Construction End: 2027
    Last Updated: 03/24/2025

    The purpose of the project is to rehabilitate the dual bridges carrying Interstate 79 over CSX & Norfolk Southern Railroads, Irwin Drive, Rudolph Avenue, and West 16th Street in the City of Erie, Erie County.

    Each of the 12-span, approximately 1570 feet long, steel plate girder bridges were built in 1983 and are currently rated in fair condition. The bridges each carry three lanes of I-79 (three lanes northbound and three lanes southbound). Approximately 10,000 vehicles use each bridge daily, of which 7% is truck traffic.

    The project includes replacement of the existing concrete deck and barriers, additional bridge rehabilitation and strengthening activities, and pavement reconstruction and resurfacing. Work will be completed using phased construction with a minimum of two lanes in each direction remaining open during construction.

    Project Location

    The bridges are located on I-79 between Exits 182 and 183A in the City of Erie, Erie County.

    The work limits also include approximately 2,000 feet of roadway to the north of the structures, ending near the West 12th Street Eastbound overpass.

    Roadway tie-in work will be necessary on Ramps E (Exit 183A) and FG (I-79 on-ramp from SR 5).
