The Montana Department of Transportation (MDT) plans to begin construction on a 3-mile section of US Highway 89 (US 89) between South Livingston and the junction of East River Road (S 540) to add a center turn lane, starting mid-March 2022, weather permitting. The project, which is expected to take five months, will improve traffic flow and local access for residents and businesses, and incorporate safety improvements. Detailed project information can be found in the Fact Sheet, and once construction begins regular updates will be posted on the Project Updates web page.
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. Once completed, the road widening project will meet the schedule set out in the planning study.
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, and a pullout area with a small cement pad just north of the East River Road junction. This will provide a safe place for truckers to rest as required by the U.S. Department of Transportation. It will also be used as a permanent location to temporarily weigh commercial motor vehicles.
Due to its proximity to the planned roadwork, the shared-use pedestrian/bicycle path that runs adjacent to US 89 will be closed periodically during construction. However, improvements to the entire 3-mile trail, which is maintained by Park County, will be included in the project.
