Project Summary
MoDOT, in coordination with the Federal Highway Administration, is finishing the re-evaluation process to update the Environmental Impact Statement (EIS) of Interstate 70 (I-70) . As work to update the Environmental Impact Statement wraps up, Improve I-70: Blue Springs to Odessa has transitioned to a Design-Build project.
Improve I-70: Blue Springs to Odessa is a $350 million Design-Build project that will add a third lane to each direction on Interstate 70 from just west of MO Route 7 in Blue Springs to approximately MO Route H. The project also includes I-70 interchange improvements at Route D in Bates City and at MO Route 131 in Odessa. The project was awarded in Spring 2025 to the Radmacher-Ideker Joint Venture team. Construction began in Sept. 2025 and is scheduled to be completed by the end of 2028.
Since its original construction more than 50 years ago, I-70 has been a vital lifeline for moving people, goods, and information across Missouri and beyond.
Project Goals
- Deliver the project by December 31, 2028 within the program budget.
- Provide an additional lane of travel in each direction on I-70 from Blue Springs to Odessa.
- Modernize I-70 while improving the existing pavement, bridges, and interchanges to enhance safety and mobility.
- Minimize construction impacts with a focus on work zone safety, communication, and construction staging while maintaining mobility.
- Provide expanded employment opportunities while developing and using a diverse workforce.
Proposal Highlights
The selected team, Radmacher-Ideker Joint Venture, was one of five shortlisted Design-Build teams. The winning proposal highlights engineering and design endeavors set out before the teams and an understanding of the local, statewide, and national importance of an improved I-70. The winning proposal includes:
- A third lane of I-70 in both directions beginning just west of MO Route 7 in Blue Springs to approximately MO Route H (mile marker 45.3), nearly seven miles past the project requirements.
- Replacement of the existing I-70 lanes with all new full-depth concrete pavement.
- Improved I-70 interchanges at MO Route D in Bates City and at MO Route 131 in Odessa.
- 14 bridge replacements.
- The team has also committed to keeping two lanes of traffic open in each direction during peak travel times.
