About the K-10 Corridor

The K-10 Corridor Capacity Improvements Project was announced in December 2021 as part of the Kansas Department of Transportation’s Eisenhower Legacy Transportation Program (IKE).

The K-10 corridor is a 16.5-mile stretch of state highway from the Douglas/Johnson County Line to I-435 in Johnson County, Kansas. Spanning the cities of DeSoto, Lenexa and Olathe, the corridor supports existing and future redevelopment in eastern Kansas and the Kansas City metropolitan area. Major educational institutions, industrial areas, new high-tech businesses, office and commercial sites and residential areas are located along this corridor.

How We Got Here

Johnson and Douglas are two of the fastest-growing counties in Kansas. K-10 is the principal highway linking these two counties. The areas around K-10 are rapidly urbanizing, with brisk commercial, industrial and residential development expected to continue. KDOT will evaluate alternative solutions to improve safety, relieve congestion, and enhance K-10’s key role in supporting existing and future development.

Project Overview

The K-10 Corridor Capacity Improvements Project will consider:

K-10 Widening

KDOT will evaluate where and when additional lanes may be needed on K‑10 from I‑435 to the Johnson/Douglas County line

Interchange Improvements

Evening Star Road, Edgerton Road, Lexington Avenue, Kill Creek Road, Cedar Creek Parkway, Prairie Star Parkway, Woodland Road, Ridgeview Road and Renner Boulevard

Additional Alternatives

Alternatives for Lone Elm Road and Clare Road

Bridge Improvements

Widening or replacement of existing bridges

System Improvements

Improvements at the K‑10/K‑7 and K‑10/I‑435/I‑35 system interchanges

Non-Roadway Solutions

KDOT will evaluate transit, technology and other non-roadway improvement opportunities during the NEPA Environmental Study

Express Lanes

One highway expansion solution KDOT is evaluating is whether adding express lanes to K‑10 could provide long-term safety, traffic flow and travel time reliability benefits. A tolling study is being completed to explore widening K‑10 to three lanes in each direction and applying a toll to the new lanes from Cedar Creek Parkway to I‑435.

KDOT has concluded express toll lanes are not the preferred solution for the K‑10 corridor because:

  • The express lanes solution would not provide a significant congestion management benefit over a toll-free solution. Based on projected traffic volumes, travel patterns and access point locations, existing and future congestion and safety issues on K‑10 can be addressed by reasonable and cost-effective toll-free improvements.
  • It would cost approximately $45 million more to construct the express lanes solution because of the additional required infrastructure. This additional infrastructure would include direct access ramps at certain locations, tolling equipment and additional pavement marking and signing. Adding toll-free, general-purpose lanes can address congestion and safety concerns on K‑10 at a lower cost.
  • Express lanes are not projected to generate significant excess revenue. Based on projected traffic through the year 2060, toll rates for the express lanes solution are anticipated to remain at or near the minimum toll rates even during peak travel times. At the minimum toll rates, revenues generated by the express lanes would likely cover costs for ongoing operations and maintenance, but would not produce significant excess revenues that could be used to offset costs for construction or be considered as a local contribution to the project.

Ways to Get Involved

Throughout the duration of the K-10 Capacity Improvements Project, KDOT will engage in a significant community engagement effort. Your feedback is important and valuable. Multiple opportunities for engagement are available.

Public Meetings

The best way to stay informed and make your voice heard is by attending hybrid or virtual meetings that will take place at several Project milestones.

Surveys

Several surveys will gauge public sentiment about various aspects of the Project.

Website & Social

You can stay involved by regularly visiting this website and KDOT’s Kansas City metro Facebook and Twitter pages. Both options allow the public to leave comments and ask questions about the Project.
