Lawrence:

A project to reconstruct the intersection of 23rd and Iowa streets has moved into the next phase. Traffic will be shifted to the south and west sides of the intersection, and each approach to the intersection will have a dedicated left turn lane and one lane for through traffic.

Crews have moved into the next phase of a project that will add a turn lane to the intersection of Sixth and Iowa streets. Sixth Street will be widened for the installation of a dedicated westbound left turn lane. Construction work will be performed on the south side of Sixth Street. Lane closures may occur between 9 a.m. and 4 p.m. on weekdays. There will be two lanes available for east- and westbound traffic before 9 a.m. and after 4 p.m. on weekdays and all times on weekends.

Intermittent, single-lane closures will occur on 6th Street from Folks to K-10 for a microsurfacing project starting Sept. 9. Existing pavement markings will be removed this week. One lane in each direction will be available for travel for motorists.

A project is underway to construct a new diamond interchange at Kansas Highway 10 and Bob Billings Parkway/15th Street. Work will take place during daylight hours, Monday through Friday, with some occasional Saturday work. Crews have begun setting traffic control for the project. Early project work will include clearing vegetation in preparation for grading work that will take place adjacent to K-10 for the new interchange. At this time, there are minimal motorist impacts, but the work has caused a need to detour the South Lawrence Trafficway trail between Sixth Street and Bob Billings Parkway. This is a popular trail route and bicyclists should take note of the detour during construction. The overall scheduled completion date for the project is early November 2015.

As part of the emergency repair work on 12th Street from Ohio to Louisiana, contractors closed the intersection of 12th and Ohio to begin replacing the storm sewer underneath 12th Street. The intersection of 12th and Ohio is expected to be closed until mid-September. Louisiana and 12th Street will remain open.

The city is installing a new water line on Mississippi Street, from Third to Ninth streets. Project timeline is June 25 to Feb. 1, 2015.

City crews are working on a waterline replacement project on Forrest Avenue from Learnard Avenue to Maryland Street and Maryland Street from E. 15th Street to Forrest Avenue. There will be no parking and the road will be closed to through traffic, Monday through Friday, from 7 a.m. to 5:30 p.m. The project is expected to last until Sept. 30.

S. Lawrence Trafficway:

In December, a three-year construction project began to complete the six-mile, four-lane Kansas Highway 10/South Lawrence Trafficway freeway. The project will move existing K-10 onto a new alignment that will begin at the south junction of the U.S. 59 and K-10 interchange and reconnect with existing K-10 in East Lawrence. Construction work on the project will be completed in phases. Each phase includes specific work and advance notification will be sent under separate cover for each phase of construction, including planned traffic impacts. The overall scheduled completion date for the project is fall 2016.
