Public Involvement

Effective public involvement is vital to good decision making. It allows MDT to deliver transportation solutions that improve safety and efficiency, protect natural and human environments, contribute to community vitality, and improve quality of life. Engaging with the public early and throughout the project development and constructions is key to MDT’s mission.

Public Meeting

The Toston Structures project is in Broadwater County, south of Townsend on US 287 near Toston. Construction begins one mile north of the existing bridges and ends just past Radersburg Road (Secondary 287) on the south end. This route is important for residents, agriculture, freight, and recreation. It is also popular for tourists traveling between Yellowstone and Glacier National Parks.

The project includes construction of 3.5 miles of new roadway, some of which will be moved over to connect to the new bridges over the Missouri River and BNSF railroad tracks. The two new bridges will be wider than the existing ones and will also include more room on the shoulder for walkers and bicyclists. Construction also includes a new culvert at Six Mile Creek, a tunnel for pedestrians under the new bridge structure, a school bus turnout (off Radersburg Road), installation of wildlife fencing, and intersection improvements. After the new roadway and bridges are completed, the old roadway and bridges will be removed. Construction is expected to take two seasons (2019 and 2020) and to be completed in the spring of 2021.

Completion of the project improves safety and addresses current and future traffic needs. The existing roadway and bridges are over 70 years old and no longer meet transportation design, environment, or safety standards. In a recent 5-year study, this stretch of road has had higher crash frequency and more severe crashes than similar roads.

Meetings were announced in local newspapers and/or through direct mailings. If you’d like to be included in the project email or text update list, please contact Becky Bey, Public Information Officer.
