Custer Avenue current photo

The Montana Department of Transportation (MDT) is in early phases of a project intended to improve West Custer Avenue from North Montana to Henderson Street.

The need for improvements on Custer Avenue is pressing. Traffic volumes are increasing on Custer Avenue, with congestion during peak times. In response, MDT, the City of Helena and Lewis and Clark County came together and prioritized improvements to Custer Avenue in Helena’s Long-Range Transportation Plan (see link in sidebar to access the full plan).

As the Montana Department of Transportation moves forward with the Custer Avenue improvements, public input is a crucial part of the process and all are encouraged to reach out with thoughts and comments on improvements to the area.

The Custer Avenue project is complex; there are many difficulties that must be addressed. There is a lengthy process that will be undertaken before construction begins.

Planning for Custer Avenue

Improvements on a busy roadway like Custer Avenue take time. We all know of a road in our community that could use work. But with 25,000 miles of roadway across Montana to consider, how does the MDT turn big projects like Custer Avenue and turn it into a reality?

As the project moves through these important phases, MDT encourages residents to reach out with thoughts on the project to help guide thinking around project elements such as detour routes, impacts to the traveling public, safety concerns and the needs of commercial and agricultural vehicles.
