The Kansas Department of Transportation is beginning work on a project at the interchange of Sixth Street (U.S. Highway 40) and Kansas Highway 10.

Work was set to begin Monday, weather permitting, and the project is expected to be complete by the end of 2024, according to a news release from the City of Lawrence.

“The project will reconfigure the current interchange to a diverging diamond interchange (DDI) and add a sidewalk with barriers for pedestrian protection down the center of the bridge,” according to the release.

“Phases I and II of the project will primarily take place west of the interchange, along U.S. 40 and East 900 Road. The current East 900 Road intersection tie-ins will close to allow room for the new interchange configuration. The north intersection of East 900 Road will be relocated to the west of its current location. The southern intersection tie-in will be permanently closed, and a cul-de-sac will be constructed for local traffic.”

U.S. 40 will be closed for about 100 days later this summer, according to the release.

In the 2024 summer months, Phase III “will require a complete closure of the interchange when U.S. 40 and the K-10 ramps are reconfigured to create the diverging diamond layout,” according to the release. “Motorists will be notified, and traffic information will be provided prior to the closures.”
