Districts Impacted
Improve I-70 KC
The Kansas City District of the Missouri Department of Transportation (MoDOT), in coordination with the Federal Highway Administration (FHWA), is improving Interstate 70 (I-70) between The Paseo Boulevard and U.S. 40/31st Street, also known as Improve I-70 KC. The project will be administered using the design-build delivery method. Construction will begin in Spring of 2025 with completion scheduled for Spring of 2028.
The re-evaluation of the Second Tier Environmental Impact Statement and the Access Justification Report have been approved by FHWA. MoDOT is in the process of acquiring the needed right-of-way.
While this project is funded separately from the Statewide Improve I-70 Program, which will add a third lane in each direction of I-70 between Blue Springs and Wentzville, Improve I-70 KC is one of several projects that will modernize the I-70 corridor across the state. Since its original construction more than 50 years ago, I-70 has been a vital lifeline for moving people, goods and information across Missouri and beyond.

Frequently Asked Questions:
Why this project is necessary and “What if we don’t do it”?
This project will help to improve reliability, safety, infrastructure, and community connectivity.
- Reliability - consistency of travel for motorists and pedestrians will continue to worsen without much needed changes to the corridor.
- Safety - crashes, involving motorists and pedestrians, will continue to increase without safety improvements.
- Infrastructure – the corridor infrastructure, including bridges, pavement, barrier, and drainage has reached the end of its service life, and needs to be replaced, rehabilitated, or upgraded. Without infrastructure upgrades planned and emergency lane closures for maintenance and repairs, will only increase, adding to further delay for motorists.
- Community Connectivity - improving pedestrian and bicycle facilities is a must and upgrades are needed immediately to better serve the public.
What is Design-Build?
Design-build is a delivery method that includes hiring one contracting team to complete the design work and build the highway improvement under one contract. MoDOT provides the project goals, budget and schedule and the contractor team completes the work. This technique has been known to significantly save time and provide cost savings.
