West Lawrence U.S. 40 (6th St.) and K-10 Interchange Improvements

Happening Now

The U.S. 40 diverging diamond interchange between John Wesley Drive and George Williams Way is now open. The video above shows the new interchange, which includes the K-10 on and off ramps, starting east of K-10 and moving west to John Wesley Drive.

Project Description

KDOT’s West Lawrence U.S. 40 (6th Street) and K-10 Interchange Improvements Project reconfigured the existing interchange into a diverging diamond interchange (DDI). A DDI enhances safety and mobility by reducing potential crash points at intersections and by allowing more vehicles to move through the intersection. The interchange includes a sidewalk with barriers down the center of the bridge to provide protection for pedestrians. The DDI is a design innovation that improves safety and mobility, often at a much lower cost, compared to conventional interchange designs. The benefits include:

• Safe and convenient bridge crossings for pedestrians and cyclists.
• Traffic signals that can be activated by pedestrians and cyclists.
• Sidewalk with barriers to cross the bridge.

More information on DDI benefits can be found on the Federal Highway Administration’s DDI handout.

Project Phasing

KDOT worked to deliver this project in phases to reduce the amount of time the interchange would be closed to traffic.

Phases 1 & 2: Improving Local Connections (Completed)

• E. 900 Road connection north of U.S. 40 reconstructed and shifted west.
• E. 900 Road south of U.S. 40 closed. Cul-de-sac constructed for local traffic.

Phase 3: Interchange Improvements (Completed)

• Full interchange closure.
• Expected completion end of 2024.
• K-10 and U.S. 40 ramps are being redesigned and rebuilt to accommodate diverging the diamond interchange.
