Billings Bypass Project: Roundabout Opening on November 24

The Montana Department of Transportation (MDT) would like to update the public on the progress of the Yellowstone River Bridge segment of the Billings Bypass project. Construction is currently progressing on schedule. The new roundabout at the intersection of Five Mile Road and Mary Street, which will ultimately connect to the new bridge, is planned to be completed, and opened for traffic on November 24. Until then, drivers should use Bitterroot Drive and Dover Road to detour around the closure.

Work zone safety reminder: The Yellowstone River Bridge construction zone is closed to the public for public safety. Members of the public interested in viewing progress may watch the construction webcam available on the project website ( or from areas within Dover Park accessible to the public. Please be aware of and comply with trail closure signs for your own safety.
