Project Overview

The Montana Department of Transportation (MDT) plans to widen a 3-mile section of US Highway 89 (US 89) between South Livingston and the junction of East River Road (S 540) with a center two-way turn lane to improve highway safety, traffic flow and local access for residents and businesses. Improving this heavily traveled and densely populated roadway section was identified as a priority in an MDT Paradise Valley Corridor Planning Study along US 89 between Livingston and Gardiner, a popular gateway to Yellowstone National Park.

Construction is expected to begin in the spring of 2022 and last approximately six months. MDT’s plans call for extending the existing center turn lane on US 89 from Merrill Lane in South Livingston to the East River Road turnoff and widening the highway's shoulders. Project safety features also will include lighting installations at the junction of US 89 and East River Road, shoulder safety rumble strips, and adding wildlife crossing signs.

Due to its proximity to the planned roadwork, the shared-use pedestrian/bicycle path that runs adjacent to US 89 will be closed during construction. However, improvements to the entire 3-mile trail, which is maintained by Park County, will be included in the project.
