 The I-70 at 5th Street & Fairgrounds Improvement Project is scheduled to begin in March 2016. This is a MoDOT managed and executed project with cost being shared between MoDOT, the City of St. Charles, St. Charles County and the federal government.  

The Fifth Street Interchange provides access to many of St. Charles County’s top attractions, retail destinations, employment centers, numerous restaurants, hotels, shops and businesses. To support ongoing redevelopment near the Fifth Street Interchange, additional work was needed to improve traffic flow and access to and from the interstate.
