I-35 SW Johnson County Interchange

The demand for improved access to I-35 in southwestern Johnson County is growing due to population growth and business expansion and development. In order for traffic to move safely, efficiently and conveniently through the Southwest Johnson County corridor on I-35, a Southwest Johnson County Interchange Access Study has been done. Currently, average daily traffic is 25,000 vehicles per day. By 2030, average daily traffic is estimated at 56,300 vehicles per day between the existing Gardner Road Interchange and the Sunflower Road Interchange. This level of traffic volume will result in congestion at critical ramp and freeway locations.

As the region continues to grow, the Kansas Department of Transportation (KDOT) must determine what improvements should be made to best handle future traffic demands, accommodate public transportation, and support economic development efforts.

The I-35 SW Johnson County Interchange Web site is an important part of this process to determine future traffic demands. Check back often to find out how you can make your voice heard and stay up-to-date on the project progress.
