Interstate 70 in Mid-Missouri

I-70 is a vital lifeline for moving people, goods, and information across Missouri and beyond. This interstate was constructed more than 50 years ago, and with the availability of additional federal and state funding, now is the time to make it fully functional for the demands of the 21st century.

Outside of Kansas City and St. Louis, Columbia is the largest city along I-70 in the state, with over 125,000 residents. Columbia is home of the University of Missouri-Columbia, which has an enrollment of 26,000 students and is the city’s largest employer.

 As work to update the Environmental Impact Statement wraps up, Improve I-70 Columbia to Kingdom City will transition to a Design-Build project. For more information about the Columbia to Kingdom City section of Improve I-70, please click here.

West: Just east of Route BB (Exit 115) to just west of MO Route 740 (Stadium Blvd.)
Central: Just west of Stadium Blvd. to just east of the I-70/U.S. Route 63 interchange (Connector)
East: Just east of the Connector to just east of Route Z (Exit 133)

The study team is currently reviewing strategies to improve aging infrastructure throughout these sections, as well as possible solutions to improve the interstate through Columbia. This includes the Connector as well as interstate crossings at: 

  • Boone County Routes J and O.
  • U.S. Route 40.
  • Stadium Blvd.
  • Business Loop 70.
  • MO Route 163 (Providence Road).
  • MO Route 763 (Rangeline Road).
  • E. St. Charles Road
  • Boone County Route Z

The MoDOT Central District, in coordination with the Federal Highway Administration (FHWA), are in the process of re-evaluating the Environmental Impact Statement (EIS) of I-70 from just east of Route BB to just east of Route Z in Boone County. A National Environmental Policy Act (NEPA) re-evaluation is necessary because the final EIS document was completed more than 15 years ago, and the existing conditions, possible solutions, potential impacts, and related mitigation measures may have changed.

Preferred Alternative Presentation

The Missouri Department of Transportation (MoDOT) held virtual and in-person Public Information Meetings in the month of November 2022 to seek feedback on a study of Interstate 70 through Columbia, including potential alternatives at the I-70/U.S. Route 63 Connector.
