Drivers who use Cottonwood and Stucky roads will face detours until fall due to construction.
The intersection, just west of Bozeman, is being replaced with a new single-lane roundabout.
Officials say construction is planned to start in late June and run through early fall 2018. The intersection will be fully closed to through traffic during construction.
According to the Montana Department of Transportation, the roundabout will address safety concerns and increase capacity as part of plans for future growth in west Bozeman.
In 2016, approximately 4,700 vehicles traveled through the intersection every day. By 2036, the number of vehicles per day at this location is expected to double.
The roundabout’s design includes the addition of sidewalks and bicycle lanes to accommodate future pedestrian and bicycle facilities on Cottonwood and Stucky roads. As a single-lane design, it will be similar in size to the roundabout in Bozeman at 11th and College streets.
According to MDT, roundabouts have been proven to minimize the amount and severity of accidents by eliminating right-angle impacts and reducing the number of conflict points. This design also enhances the capability of an intersection while simultaneously providing a traffic calming effect.
