Project Summary

The Missouri Department of Transportation (MoDOT), working with its consultant Bartlett & West, is preparing for an interchange improvement project on U.S. Route 61 in Lincoln County, located at the Routes B and E intersection near Auburn. Improvements to this location will include: 

  • Intersections and safety improvements at U.S. 61 and Routes B/E intersection
  • Elimination of the U.S. 61 at-grade crossings at Routes B/E and Shannon Lane/Wilson Road
  • The existing U.S. 61 northbound lanes will be converted to an outer road, and new U.S. 61 northbound lanes will be constructed in the existing median
  • Construct a new interchange, just north of existing Routes B/E intersection. The interchange design will include:
    • A new bridge consisting of 12-foot lanes with 4-foot shoulders 
    • Two roundabouts, located on the east and west ramp terminal intersections

Environmental studies will be completed as part of the project.

Project Plans

Aerial image of the Routes B/E and U.S. 61 intersection in Lincoln County. A project overlay shows the interchange location offset just to the north of the current location with 2 roundabout intersections at the east and west ramp terminals. The northbound lanes of U.S. 61 will be constructed in the center median. The existing northbound lanes will become a new outer road serving local businesses and residents.
Aerial image of the U.S. 61 at-grade crossing at Shannon Lane/Wilson Road that will be eliminated. The existing northbound lanes will become a new outer road serving local businesses and residents. Wilson Road will tie into the new outer road. This at-grade cross-over will be removed and Wilson Road and Shannon Lane will no longer have direct access to U.S. Route 61.

Frequently Asked Questions

 

How much does the project cost? 

Approximately $22.5 million

 

What are the anticipated impacts? 

Construction details have not been finalized at this time. MoDOT will work with residents and business owners to ensure access is available during construction.

 

Why propose the use of Roundabouts at the ramp terminals of the interchanges?

A roundabout is a one-way circular intersection that channels traffic around a central island without traffic signals. Roundabouts are a great alternative to a signalized intersection when a high volume of traffic needs to get through with the least amount of inconvenience.

While signalized intersections have approximately 20-30 conflict points, or spots where vehicles could collide, roundabouts reduce that number to eight. Fewer conflict points, combined with slower speeds and calmer traffic, can translate into as much as 76% fewer crashes. Because roundabouts tend to have fewer severe crashes than signalized intersections, they have fewer crash-related injuries as well.  View the Roundabout Handout to learn more.

Will the road be closed during construction?  

Various traffic impacts will be in place as the project progresses. MoDOT will make every reasonable effort to reduce delays due to construction. Customers can anticipate temporary traffic impacts throughout the project. More information regarding traffic impacts will be shared through news releases and social media for each stage of construction as details become available.

 

Will MoDOT need to acquire any right of way?   

Yes. Beginning in Fall 2026, MoDOT's Right of Way staff and consultants will begin the process of contacting property owners for any necessary right of way needed for the project. Right of way discussions are anticipated to continue through 2027.
