Missouri officials recently selected a design-build team of Millstone Weber and Jacobs for the first $405-million project planned as part of a program to widen and improve Interstate 70 across the state. Lawmakers budgeted $2.8 billion for six projects covering nearly 200 miles of the highway between the Kansas City and St. Louis metro areas.
The scope of this first project covers the addition of a third lane in both directions and concrete paving of all lanes along a 20-mile section of I-70 between Columbia and Kingdom City, Mo. The project also includes reworking the U.S. 63 interchange with two new ramps and four roundabouts, plus reconstructing the U.S. 54 interchange with two new bridges. The inside and outside shoulders would also be widened.
