Project Description
The Kansas Department of Transportation (KDOT) and the City of Olathe are partnering to resolve challenges on one of the region's most congested corridors. The I-35, Santa Fe, and Old 56 Highway Corridor Improvements Project, known as "I-35 Santa Fe Forward," will improve traffic operations and safety of I-35 from Old 56 Highway (southern limit) to 119th Street (northern limit) and on the major arterial of Santa Fe Street in the city of Olathe, Kansas.

- Addressing access management issues on Santa Fe Street
- Replacing infrastructure that is at the end of its service life
