MoDOT’s Statewide Improve I-70 Program continues to make progress. The first contract of this historic program, from Columbia to Kingdom City, is already under construction. Between Routes J and M in Callaway County, a barrier wall is in place and workers are preparing the median for future pavement. This first contract includes a total of 20 miles of I-70 between Route 54 in Kingdom City to Route 63 in Columbia. See photos of the construction progress here.
Procurement efforts have started for the next contract on I-70 between Warrenton and Wentzville. Three Design-Build teams have been selected to compete for the contract. It is anticipated the proposals will be presented to the Missouri Highway & Transportation Commission (MHTC) for selection of the best value proposal later this fall.
MoDOT has been working on the best plan to be efficient and innovative in how the 200 miles of I-70 will be delivered. As of August 2024, the Improve I-70 individual project limits have been updated and now include eight total project segments across the state. These various contracts will be awarded through 2029. The total completion of the nearly 200 miles of I-70 is anticipated by the end of 2030.
