At its November meeting, the Missouri Highways and Transportation Commission (MHTC) selected the Millstone Weber team as the apparent best-value proposer and Design-Build contractor of the sixth project in MoDOT’s Improve I-70 Program, between Kingdom City and Warrenton. The team consists of contractor Millstone Weber, designer Jacobs, Inc., and key partner WSP.
Improve I-70: Kingdom City to Warrenton is a $583 million project that will add a third lane to each direction and make other improvements along 44 miles of Interstate 70 from Kingdom City to Warrenton.
The winning proposal includes:
- A third lane in each direction of I-70, as well as the replacement of all existing I-70 pavement between Kingdom City and Warrenton with new full-depth concrete pavement.
- Three bridge replacements.
- Six bridge rehabilitations.
- A fourth lane along eastbound I-70 at Mineola Hill (climbing lane).
- Redesigned Norfolk Southern Railroad Crossing at High Hill.
MoDOT will host public information meetings in early 2027 as these details are available. Construction is scheduled to begin in spring/summer 2027 with an anticipated completion in late 2030.
Only two Improve I-70 projects remain in the procurement process: Improve I-70: Odessa to Concordia and Improve I-70: Concordia to Boonville. Both are anticipated to be awarded by May 2027 with statewide completion of the entire Improve I-70 Program anticipated in late 2030.
