This map shows the area around the Sixth Street-Kansas Highway 10 interchange scheduled to be closed to traffic starting Monday, June 3, 2024.

The Kansas Department of Transportation plans to begin the next phase of its project at the U.S. Highway 40-Kansas Highway 10 interchange in Lawrence on Monday.

KDOT announced the next phase of the project in a news release on Wednesday. It will require the interchange to fully close while a new diverging diamond layout is constructed. According to the release, Sixth Street will be closed between the new John Wesley Drive and George Williams Way, and all K-10 on- and off-ramps will be closed to traffic.

The K-10 ramps and at least one lane in each direction on U.S. Highway 40 are expected to partially reopen in September, and the new diverging diamond interchange is scheduled to be fully open by the end of October.

As the Journal-World has reported, this work is part of KDOT’s $14 million interchange project at Sixth Street and K-10. During the scheduled closure, motorists can follow a signed detour along Interstate 70 or K-10, or use alternate routes that aren’t marked.

The diverging diamond interchange being added in Lawrence crosses two directions of traffic from the non-freeway road to the opposite side on both sides of the bridge at the freeway, requiring traffic on the freeway overpass and underpass to briefly drive on the opposite side of the road from what is customary.
