An overview of detour routes set during the Grangeville Main Street/State Highway 13 repaving work set to begin Friday night, July 15. Detours will be in place during night work (9 p.m. - 6 a.m.) and two lanes open during the day.

— Construction kicks into high gear Friday night, July 15, as crews begin a 24-7 schedule to expedite repaving along Main Street/State Highway 13.

Contractor, Knife River, will begin milling Grangeville’s Main Street Friday night, starting at 9 p.m. from U.S. Highway 95 to Idaho Avenue, and work until 6 a.m. Saturday, July 16. Milling will continue Saturday night, from 9 p.m. to 6 a.m. Sunday morning from Idaho Avenue to the junction with Mt. Idaho Road.

Traffic will be detoured through the project during these nine-hour shifts. Vehicles will not be able to park along Main Street during repaving work – tentatively set for completion July 24 – however, access will be maintained as best as possible, according to Idaho Transportation Department project manager Janet Zarate, and two lanes of travel will be maintained through the day.

Knife River recognizes the disruption the project entails for Grangeville residents, “and they really want to get in, get the project done as efficiently as possible and get out,” Zarate said.

The new project schedule, up to 24-7 operations, sets final completion for early August, saving several weeks on the prior Aug. 25 “done” date.

Crews will shift equipment and manpower to Main Street in force on completion of the U.S. 95 in-depth resurfacing project set for completion prior to Wednesday, July 20. Unlike U.S. 95 that is undergoing a CRABS (Cement Recycled Base Stabilization) resurfacing, Main Street will have a less intensive asphalt surface milling and repaving.

Under this new schedule, this will allow Knife River to provide for one continuous top layer of repaving along the project, avoiding seams and consistency issues having to do this in separate placements, according to Zarate.

“This will benefit the folks of Grangeville,” she said. “They’re going to complete the project more quickly, and we’ll get a better project by working up to 24 hours a day, seven days a week.”

Repaving work on the $2.3 million U.S. 95 and Main Street/SH13 project started in earnest on July 6.
