Subsurface borings in preparation for Improve I-70 project

Expect lane closures on U.S. Route 63 and I-70 in Columbia

BOONE COUNTY – Contractors with the Missouri Department of Transportation will be performing subsurface boring operations in both directions on sections of Interstate 70 and U.S. Route 63 beginning on Wednesday, April 17.  This work will require the following intermittent closures of a single lane:

  • Crews will reduce northbound and southbound Route 63 to ONE LANE in each direction between approximately Broadway and I-70 from 9 a.m. until 3 p.m. daily beginning on Wednesday, April 17, through Monday, April 22. One lane of traffic will remain open in each direction at all times.
  • Crews will have nightly intermittent lane closures along both eastbound and westbound I-70 at approximately mile marker 129.6, just east of Route 63 in Columbia from 7 p.m. and 6 a.m. each evening beginning on Monday, April 22, through Friday, April 26. One lane of traffic will be open in each direction at all times.

This work is part of the design process ahead of construction on Improve I-70: Columbia to Kingdom City, the first project in MoDOT’s Statewide Improve I-70 Program. Borings allow for a detailed examination of the subsurface conditions related to bridge piling or drilled shafts. By studying the samples obtained in the borings, the designers can make informed decisions on design and material elements for the engineering plans to expand I-70 to three lanes in each direction. Construction of this first section of I-70 between Columbia and Kingdom City is scheduled to begin in summer 2024 with an anticipated completion in late 2027.

Improve I-70: Columbia to Kingdom City includes new concrete pavement on all three lanes of I-70 in each direction for the 20-mile section between Columbia and Kingdom City and improved interchange designs at the U.S. 63 and U.S. 54 interchanges at I-70. Additionally, the first awarded contract proposal includes:

  • Improvements at the U.S. 63 and I-70 interchange:
    • Two new direct connection ramps (northbound U.S. 63 to westbound I-70 and eastbound I-70 to southbound U.S. 63)
    • Four new roundabouts
  • Improvements at the U.S. 54 and I-70 interchange with two new bridges and a new and improved interchange.

Missouri’s FY2024 budget from the General Assembly signed into law by Governor Parson provides $2.8 billion in General Revenue for the costs to build a third lane of I-70 across the state. The program will plan, design, construct, reconstruct, rehabilitate, and add a third lane in each direction on nearly 200 miles of I-70, from Blue Springs to Wentzville.
