I-70/Route 54 Kingdom City Interchange Study & Re-Evaluation of Environmental Assessment
The Missouri Department of Transportation (MoDOT) is working with a consultant team to prepare a traffic and safety study that will explore improvements to the interchange of Interstate 70/U.S. Route 54 in Callaway County.
The goal of the study is to identify a preferred alternative design for the interchange that improves safety and mobility through the corridor, provides access to nearby businesses and promotes economic growth in Kingdom City, Missouri.
As part of the planning stages for the improvements to this interchange, MoDOT is accepting public comments as part of a re-evaluation of an environmental assessment completed in 2005. The results of that study can be found at improvei70.org/environmental_6.htm. Individuals or organizations wishing to comment can do so by using the web form below.
Comments must be submitted on or before Monday, October 11, 2021.
When: The study kicked off in August 2021 and is scheduled to conclude in May 2022. A public meeting is anticipated in January 2022.
Cost: Estimated construction cost is $6,695,000.
Work Taking Place: In addition to a safety study and preferred alternative, the team is re-evaluating an environmental assessment completed in 2005 that resulted in a Finding of No Significant Impact (FONSI) for the Second Tier Final Environmental Assessment (EA) of Section of Independent Utility 6 for the improvements to the I-70/US 54 interchange. MoDOT expects the re-evaluation to be completed in May 2022.
Traffic Impact: None during the study phase.
The US-54/I-70 interchange serves popular destinations in mid-Missouri, including Jefferson City and Lake of the Ozarks, and features numerous services for car and truck traffic. Over the years, development has strained the interchange’s capacity and reduced the effectiveness of access points along US-54.
Other factors impacting capacity include the nearby North Callaway School Campus and the potential addition of a distribution center to the northwest. As part of their Improve I-70 Study Final Second Tier Environmental Assessment (May 2005), MoDOT selected a preferred alternative that entailed modifying the ramps and relocating the US-54 median crossings further from I-70. Other alternatives included offset alignments and a variety of interchange types. Primary concerns were impacts to local businesses and restrictions related to the Kansas City Southern Rail line paralleling US-54 just west of the interchange.
More than 15 years have passed since that initial study, and stakeholder concerns and priorities have evolved during that time. MoDOT and the consultant team will revisit possible solutions to improve the intersection with area stakeholders and businesses throughout the study before a preferred alternative is recommended in February of 2022.
