Project Summary
MoDOT, in coordination with the Federal Highway Administration, is finishing the re-evaluation process to update the Environmental Impact Statement (EIS) of Interstate 70 (I-70) between U.S. 63 and U.S. 54.
As work to update the Environmental Impact Statement wraps up, Improve I-70 Columbia to Kingdom City has transitioned to a Design-Build project. Millstone Weber has been selected as the best-value proposer and Design-Build contractor of Improve I-70: Columbia to Kingdom City. This $405 million fixed-cost contract includes $123 million previously programed for the interchanges at U.S. 63 and U.S. 54. The winning proposal includes new concrete pavement on all three lanes of I-70 in each direction for the 20-mile section between Columbia and Kingdom City, wider inside and outside shoulders, and improved interchange designs at the U.S. 63 and U.S. 54 interchanges at I-70. Additionally, throughout construction two lanes of travel will be available for both directions of I-70 during peak hours.
This project is one of several projects which will widen the I-70 corridor across the state. Construction began in July 2024 and is anticipated to be completed in late 2027.
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.
