STC-3944, lake fork creek bridge rehab, valley CO

The Federal Highway Administration awarded the Idaho Department of Transportation $401,374.50 on February 5, 2026, for bridge rehabilitation work under the Bridge Formula Program (CFDA 20.263). The award funds rehabilitation of the Lake Fork Creek Bridge in Valley County, Idaho, which exhibits spalled areas on the exterior flanges of the girders and undermining of the abutment cap. As traffic demand over the bridge is expected to increase, these defects require remediation to address accelerating deterioration. Work is performed in Idaho with an ultimate completion date of July 31, 2031. The Bridge Formula Program apportions funding to states via formula based on the relative costs of replacing bridges classified as in poor condition and rehabilitating bridges in fair condition, for use on highway bridge replacement, rehabilitation, preservation, protection, or construction projects on public roads.
