Preferred Alternative
As part of the Supplemental Environmental Impact Statement (SEIS) process, The Kansas Department of Transportation (KDOT) and the Federal Highway Administration (FHWA) have evaluated the reasonable alternatives and recommend the Add Capacity Freeway Alternative as the Identified Preferred Alternative because it best meets the purpose and need for the corridor.
The Preferred Alternative will:
- Add two lanes to SLT to create a four-lane divided highway.
- Build an interchange at 27th Street and Wakarusa Drive. The traffic signal will be removed and access to the local streets will be provided via new interchange ramps. New bridges will carry SLT traffic over Wakarusa Drive, allowing local traffic, bicyclists, and pedestrians to cross SLT safely.
- Reconfigure the interchange ramps at I-70 and SLT to allow traffic to move easily from SLT to I-70. The reconfiguration will keep and improve access to and from Farmer’s Turnpike to SLT & I-70.
- Realign SLT through the Clinton Parkway interchange to make the existing curve less sharp.
- Reconfigure the interchange at U.S. 59.
- Accommodate for future widening in the median, Transportation Demand (Smart Tech) Management Strategies, and transit and bicycles/pedestrians.

Improvements to West Lawrence U.S. 40 (6th Street) & K-10 Interchange
KDOT is also making improvements to the West Lawrence U.S. 40 (6th Street) and K-10 Interchange. The project will reconfigure the existing interchange into a diverging diamond interchange (DDI). A DDI is an interchange that will allow traffic to cross to the opposite side of the road, making left turns easier and safer when turning onto or off K-10. The interchange will include a sidewalk with barriers down the center of the bridge to provide protection for pedestrians.
