The Missouri Highways and Transportation Commission (MHTC) has selected the Millstone Weber Team as the apparent best-value proposer and Design-Build contractor of the next 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. Negotiations to finalize the contract are currently in progress.

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.

This project is the sixth in a series of projects which will widen and improve the I-70 corridor. Missouri’s FY2024 budget from the General Assembly and signed into law by the governor provides $2.8 billion in General Revenue and bonding authority for the costs to build a third lane of I-70 across the state.

The program will plan, design, construct, reconstruct, rehabilitate, and add a third lane in each direction on nearly 200 miles of I-70, from Blue Springs to Wentzville.

The selected team was one of four shortlisted Design-Build teams. Their 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 all 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.
