Motorists using Kennewick's Clearwater Avenue west of Highway 395 might consider alternative routes for a few weeks.
The four-lane thoroughfare will be resurfaced between Edison and Highway 395, forcing lane closures sporadically 24 hours a day.
City engineer Dan Kaufman said the project will result in the closing of one lane in each direction for about 1.5 miles while crews grind, patch and pave the road.
"(Clearwater Avenue) is the No. 2 highest-traveled street in the city. It's exceeded its normal life," Kaufman said.
Weather permitting, the project should be finished by the first week in October, Kaufman said.
This week, crews have been preparing pedestrian ramps at intersections for improvements. Asphalt grinding will start Monday evening. Patching begins Tuesday, Kaufman said.
Grinding is scheduled for evenings during the next weeks. Crack repair and patching will take place during the day. Work will be staged to have the least affect on daytime traffic, Kaufman said.
Motorists are advised to use caution, slow down and be alert while traveling through the construction area.
