New Interchange at Route 54/Route W in Miller County

Scheduled for Completion December 2021

A contractor for the Missouri Department of Transportation will build a new interchange at the intersection of U.S. Route 54 and Business Route 54/Osage Hills Road in Lake Ozark. This is an effort to improve safety at this location. The most recent data states that 32 crashes took place during the last five years at that intersection. 

When: Construction on the new interchange will begin the week of Monday, February 3, 2020. Work is expected to be completed by December 2021. 

Cost: Emery Sapp and Sons submitted the low bid of $9,711,377. 

Work Taking Place: The new interchange will replace the existing signaled intersection in an effort to increase traffic safety and improve traffic flow. The project will involve building two new bridges on Route 54, just west of the existing intersection, as well as three roundabouts near the interchange. Crews will also complete grading and paving to incorporate the intersections of Route 54, Business Route 54, Miller County Route W and Osage Hills Road into the interchange.

Traffic Impact: Occasional lane and road closures will be necessary as part of this project on all impacted roadways. MoDOT will alert motorists to closures through the Traveler Information Map, signs, local media, social media, and this website.
