The Kansas Department of Transportation says a patching and concrete replacement project on I-70 in Riley and Wabaunsee counties has been delayed a week and will now start March 27.

The work will stretch from the Riley/Geary county line to K-30 in Wabaunsee County but will not impact bridges and bridge approaches in the corridor. Crews are planning work in both directions in roughly 4-mile stretches of the interstate, resulting in lane reductions, width restrictions and reduced speed limits of 60 mph. On and off ramps will remain open during the project.

KDOT says work will take place Monday through Friday during daylight hours. Lane closures will remain in place when crews are not working, with work estimated to be completed by mid-June.

Emery Sapp & Sons Inc., of Columbia, Mo., is the prime contractor on the $2.5 million project.
