Starting Monday, crews from Ameren Missouri will be working in the 4900 to 5200 blocks of Business 50 West at Apache Flats as the first step of the improvement project for the road takes place.
They'll be working to relocate power lines, and most of the work will be off the north side of the road.
Periodic closures of the westbound lane will be necessary to allow room for equipment.
Traffic control signaling devices will be in place, and traffic will be shifted in other lanes to get vehicles through the work zones.
Cole County Public Works officials said they do not expect any delays in traffic due to this work. The work should be completed in two to three weeks.
