New I-70 Interchange
The new interchange was fully funded with a sales tax passed by residents in the city of Warrenton. Once the project is complete, MoDOT will own and maintain the interchange. In exchange, the City has agreed to assume responsibility of ownership and maintenance of Route MM to Main Street and the south outer road from Denny's to the new interchange.

Groundbreaking Ceremony
