MoDOT and St. Charles County officials reviewed the feedback of more than 3,000 comments. The responses were received during a public comment period from December 2020 to June 2021.

The procurement process will begin shortly, and MoDOT will present the final design by February 2022. Construction is anticipated to begin next spring.

“We heard the public’s concerns about a potential one-way conversion of the outer roads to improve the safety and congestion issues. We went back to the drawing board to see if we could improve the interchanges while keeping a two-way outer road system,” said Stacey Smith, MoDOT project director.

“Based on this, we have decided that leaving all options on the table will give the public the best possible project. Our team listened to the public, and we’ve dramatically changed the priorities of this project. Connectivity is now the number one goal.”

Better connectivity will make access to local businesses and homes easier. The current roadway design and inefficient traffic flow have restricted connectivity for over a decade. In addition, this project is a regional priority due to the high crash rate, including 3,000 crashes in the past five years.

This section of I-70 was built in the 1950s and 1960s, making it one of the oldest sections of interstate in the country and one of the busiest in Missouri. The congestion at the interchanges often causes traffic to back down the off-ramps to I-70 during rush hours. MoDOT says to improve connectivity, safety and efficiency, the agency is looking at both the entire corridor and local system and is open to all solutions for the interstate, outer roads, interchanges and side street access.

The project is a joint project with St. Charles County, who contributed $10 million of the $62 million cost of the reconstruction.
