Improve I-70 Warrenton to Wentzville

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) in Warren and St. Charles counties. As work to update the Environmental Impact Statement wraps up, Improve I-70 Warrenton to Wentzville will transition to a Design-Build project. For more information about this portion of the Environmental Impact Study (Montgomery, Warren, and west St. Charles counties), please click here. The award of this contract is scheduled for late 2024 and construction could begin by spring 2025

This project is scheduled to include the following improvements:

  • Add a third lane of travel to eastbound and westbound I-70 between Warrenton and Wentzville.
  • Realignment at the railroad bridge on I-70 between Wentzville Parkway and Route Z.
  • Interchange improvements at I-70 and I-64/Route 61
  • Add a third lane of travel to eastbound and westbound I-64 between I-70 and Route K.

The third lane of I-70 from Warrenton to Wentzville is being funded through General Revenue funds. The Improve I-70 project will also include the realignment at the railroad bridge between Wentzville Parkway and Route Z, improvements at the I-70/I-64 interchange and adding the third lane on I-64 from I-70 to Route K, which are being funded through previously programmed MoDOT STIP projects. 

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.

MoDOT is requesting Statements of Qualifications for Project #2
