Lawrence

• Drivers on the Kansas Turnpike should expect slight delays leading up to and immediately following a scheduled blast set for 2 p.m. Tuesday on what remains of steel supports for an old bridge over the Kansas River. Explosives will be used, and the Kansas Highway Patrol will be scheduled to conduct “rolling roadblocks” to slow traffic enough in both directions to keep traffic off the new river bridge as the blast approaches.

• Reconstruction work continues at the intersection of North Second and Locust streets, in North Lawrence. One lane of North Second remains closed for traffic heading south through the intersection. Both lanes are closed for traffic heading north. Northbound vehicles follow a detour that includes Elm, North Third, Locust and — crossing Union Pacific Railroad tracks — Lyon streets. State transportation officials expect the detour to last into late January.

• Drivers may face slow traffic periods as construction continues for a new U.S. Highway 59 between Lawrence and Ottawa. While the section in Douglas County remains an active work zone, the section in Franklin County is expected to open to traffic in the spring.

Douglas County

• Douglas County Road 9, or East 1500 Road, remains closed from the Kansas Turnpike to U.S. Highway 24-40. Crews hired by the Kansas Turnpike are continuing bridge-construction activities. The closure is scheduled to last until late spring.

U.S. Highway 69

• A section of U.S. Highway 69 in Wyandotte County, known as the 18th Street Expressway, continues to be limited to one lane in each direction from 7 a.m. to 7 p.m. daily as crews paint the bridge. Work is expected to last into late March.
