The Kansas Highway 10 construction project is back on.
Rumble strips and paved roadside shoulders are coming to that stretch of K-10 that runs from the edge of Lawrence to the Johnson County line.
Accompanying the safety improvements will be a new 1.5-inch-thick layer of pavement, giving the popular four-lane highway a fresh surface for the first time in 12 years.
The work starts at 9 a.m. Monday. It had been scheduled to start twice before, but then postponed.
“We’ll do the best we can to minimize the frustration for everybody,” said Jason Van Nice, the project’s construction manager for the Kansas Department of Transportation.
Crews from Perry-based Hamm Construction will handle the $4.3 million job, scheduled to be finished in early November.
Beginning Monday, crews will start patching areas that have major damage, starting at the eastern edge of Lawrence and working their way east. They will patch in one lane for eastbound traffic at a time; after that, they’ll switch over to lanes used by traffic heading back into Lawrence.
Expect patching to last a week, with crews working mostly during daytime hours.
“We’ll probably be moving around quite a bit that first week,” Van Nice said. “We’ll fix the really bad spots so they don’t get any worse.”
After that, crews will turn their attention to grinding off the top inch of the highway’s asphalt — again, one lane at a time on one side of the highway — before laying down a thicker layer of fresh material, often the same day. Much of that work will be done after dark, Van Nice said, to minimize traffic disruptions.
The highway typically handles more than 25,000 vehicles a day, including more than 1,100 heavy commercial trucks.
“Most of the big work will be overnight,” Van Nice said.
Crews will be allowed to work seven days a week, but — by contract — they will be prohibited from working or having any lanes closed during specific periods of high traffic:
• From 6 a.m. to 9 a.m. and from 3 p.m. to 6 p.m. weekdays, considered peak travel times for commuters.
• Saturdays when Kansas University has a home football game: Oct. 15, Oct. 22 and, if the project isn’t finished yet, Nov. 12.
The speed limit will be reduced from 70 mph to 55 mph in areas where crews are working. No more than one lane of traffic, in one direction, will be closed at any one time, Van Nice said.
Some ramp closures may cause detours, Van Nice said, but crews will attempt to keep ramps open even while repaving work is being conducted in the area. Any work involving a ramp closure will be done overnight.
“We’re trying to minimize the inconvenience,” Van Nice said.
