    Project Overview

    County: Crawford
    Municipality: Rockdale Township
    State Route: 408
    Local Name: Route 408 over Mohawk Run
    Project Type: Bridge Replacement
    Proposed Construction Start: 2026
    Proposed Construction End: 2026
    Last Updated: 03/07/2025

    The proposed scope of work includes a bridge replacement of the existing structure that carries Route 408 over Mohawk Run in Rockdale Township, Crawford County.

    The existing concrete bridge was built in 1930. It is rated in poor condition. Approximately 1,200 vehicles a day us the bridge, on average.

    Work will involve replacing the concrete T-beam bridge with a reinforced concrete box culvert and minimal paving of each side of the bridge. No major change in roadway grade anticipated, which will include shoulder backup. The existing pavement will be milled and overlaid to tie into the proposed structure. Right-of-way acquisition is anticipated at the structure.

    The estimated construction cost is estimated between $1 to $2.5 million and will be funded federally. This project is funded at least in part by the Bipartisan Infrastructure Law (BIL).

    Project Location

    The bridge is located on Route 408 approximately 750 feet east from the intersection of Route 408 and Greytown Hills Road (Route 1031).

    Traffic Impacts

    A detour will be required during construction and is expected to be in place for approximately four months.

    The proposed 27.5-mile detour will be posted using Route 408, Route 86, Route 198, and Route 77.
