When will construction take place?
Construction for the Briggs Coulee detour began in the Spring of 2024. Construction is underway and was substantially completed in fall 2026.
What type of bridge will be constructed?
The bridge styles chosen for each project location were carefully selected to meet the unique needs of each site and include single-span bridges, multi-span bridges, box culverts, arched culverts, and pipe culverts.
Who is working on this project?
This project is a joint effort between the MDT and other local, state, and federal resource agencies. This project is being delivered as a Construction Manager/General Contractor (CM/GC) project, which means that the design engineer (DOWL) and the CM/GC (Kiewit) are working closely with the owner (MDT) to streamline project delivery and provide efficiencies during design and construction. KCI/Krebs is also supporting the project as the Independent Cost Estimator.
Why do the structures need to be replaced?
Toward the goal of Vision Zero, these bridges are being replaced to keep the traveling public safe. Because of the advanced deterioration and the load-posting restrictions of the existing structures, rehabilitation was not practical. Nine of the bridges were constructed prior to 1940 and the timber structures had reached the end of their useful and serviceable life.
Will livestock passages be maintained?
Yes, MDT has maintained wildlife/livestock passage where appropriate.
What is the funding source?
Funding for this project is through the National Highway Block Grant Program, administered by the Federal Highway Administration, which provides funding to states and localities for transportation improvement projects.
