The Missouri Highways and Transportation Commission (MHTC) has selected the Radmacher-Ideker Joint Venture team as the Design-Build contractor of the next project in MoDOT’s Improve I-70 Program. The joint venture team consists of contractors Radmacher Brothers Excavating Co., Inc. and Ideker Inc., with designers Wilson and Company, Inc.

Improve I-70: Blue Springs to Odessa is a $350 million fixed-cost contract that will add a third lane to each direction and make other improvements to Interstate 70. The Design-Build contractor team has also committed to extending the third lane in both directions to mile marker 45.3, nearly seven miles past the project requirements.

This project is the third in a series of projects which will widen and improve the I-70 corridor. 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, Radmacher-Ideker Joint Venture was one of five shortlisted Design-Build teams. The winning proposal includes:
-Constructing 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.

The next steps include finalizing the contract, and the contractor team will be doing more detailed design of the roadway and interchanges and outlining the construction schedule with traffic control plans. MoDOT will host public information meetings this summer as these details are available. Construction is scheduled to begin in September 2025 with an anticipated completion in late 2028.
