Montana Department of Transportation – Broadus Interchange – Miles City

Located in southeast Montana, Miles City is an urban center founded on agriculture. The city’s Broadus Interchange, originally constructed as a “farm interchange,” provided community access to the new interstate highway system. Over half a century later, Miles City swelled in size to become one of the largest cities in the region and the county’s seat. Yet the Broadus Interchange is still the city’s “gateway,” providing access to and from the interstate for residents, visitors, and the surrounding rural communities relying on Miles City for essential services. However, the city’s growth created traffic congestion issues. That is why the Montana Department of Transportation launched and completed a $15.6 million project to rework the interchange – a project that included the reconstruction of bridges to meet capacity and new standards and two new roundabouts, which improved traffic flow and improved sidewalk access for pedestrians. These improvements reduced traffic congestion while increasing safety for both motorized and non-motorized travel alike.
