news Project Summary

Improve I-70: Kingdom City to Warrenton will be a $581 million Design-Build project that will improve the 44-mile stretch of Interstate 70 from Kingdom City to Warrenton. 

This project is scheduled to be awarded in November 2026. Construction is anticipated to begin in Spring/Summer 2027 with an anticipated completion in late 2030.

This project is one of several which will modernize the I-70 corridor across the state. 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.

Pre-Qualified Teams

MoDOT has received Statements of Qualifications (SOQs) from the teams interested in competing for the contract to design and construct the sixth project of MoDOT’s statewide Improve I-70 Program, Kingdom City to Warrenton.

The pre-qualified teams are as follows:

  • Ames Construction
    • Ames Construction, Parsons Engineering
  • Improve 70 East Alliance
    • Emery Sapp & Sons, Clarkson Construction Company, Wilson & Company, and Bartlett & West
  • Millstone Weber Team
    • Millstone Weber, Jacobs Engineering, and WSP
  • Missouri Interstate Constructors
    • William Charles Construction, Michels Road & Stone, Inc., KCI Construction, AECOM, and TYLin

MoDOT will issue the Request for Proposals in late June 2026 to these teams to work through development of their Design-Build proposals for the project. The department will work through the procurement process with these teams, who will submit their proposal for the potential selection of the winning contract in November 2026. Construction could start as early as Spring 2027. There are still opportunities for additional consultants and subcontracting firms to be added to each team.
