145TH n bridge replacement project

The Federal Highway Administration awarded the Local Highway TECH Assist Council $410,000 on March 19, 2026, under the Bridge Investment Program (CFDA 20.264) to study and recommend a replacement alternative for the 145th N Bridge over the Snake River in Idaho. The project addresses structural deficiencies in the 1967-design bridge, which carries fair to poor National Bridge Inventory ratings. The award funds analysis of improvements including wider lanes to accommodate traffic and agricultural equipment, expanded shoulders, space for non-motorized users, and deep foundations to enhance structural resiliency and public safety. Local Highway TECH Assist Council, a State Government Council of Governments entity headquartered in Boise, Idaho, serves as the recipient. The period of performance extends through September 30, 2027. Work is performed in Idaho. The Bridge Investment Program is a competitive, discretionary grant program established under the Infrastructure Investment and Jobs Act that focuses on reducing the number of bridges in poor or at-risk fair condition and expands direct applicability to local and tribal governments.

Project description

This project will study and recommend a replacement alternative for the 145TH n bridge over the snake river. Improvements to the 1967 design are necessary to improve public safety and address the fair to poor national bridge inventory (NBI) ratings for the structure. These improvements include wider lanes to accommodate traffic (including agriculture equipment), shoulders, space for non-motorized users, and deep foundations to improve overall structural resiliency.
