Dodson South Canal
The bridge over Dodson South Canal, located approximately 1.5 miles south of Dodson on Hwy 204, will be replaced with a new structure. To maintain the safety and effectiveness of the route, the existing bridge, which has been identified as being in poor condition, will be replaced with a 14-foot by 10-foot double-cell concrete box culvert. The roadway next to the new structure will also be reconstructed and other minor enhancements will be considered to improve safety at the bridge location.
Different detour options are being explored for anticipated construction during late Fall 2023 or early Spring 2024. Construction will occur when water is not in the canal. The length of construction depends on the detour option selected but could run as long as three months. The Montana Department of Transportation would like to share different detour options with the community and stakeholders and identify the best detour option for the community. Two detour options have been identified:
- One option includes a temporary, single-lane detour bridge until the new structure is completed and opened to traffic. An on-site detour is estimated to cost $150,000 or more.
- The second option includes a 22.5-mile detour (an increase in travel distance of 15 miles) to South Wagner Road via Aklaki Road. This option is estimated to cost around $20,000.
- A "no-build" option is not feasible due to the current structures' poor condition.
The highway provides local access to US Route 2 and Hwy 191. It is an identified mail route and is used frequently to move agricultural equipment and products.
