A newly announced $600 million contract to widen and rebuild Interstate 70 from Wentzville to Warrenton is the largest ever awarded by the Missouri Department of Transportation.

The work, which will start next spring and continue until the end of 2028, will be the second of six phases of a $3 billion revamp of a nearly 200-mile corridor of I-70 from Wentzville to suburban Kansas City. Work on the first, $405 million segment, from Columbia to Kingdom City, began earlier this year. Millstone Weber is leading that effort.
