Sealing highway surfaces will help preserve the pavement.
More than 50 miles of several highways will receive a sealing treatment, from Lewiston to Grangeville and Orofino to Kamiah. As contractors apply sealcoats, drivers can expect alternating traffic on loose gravel and short delays. Each segment is expected to take up to four days, followed by intermittent work to broom and stripe the improved surface.
Crews will start on ID-13 from Grangeville to Harpster Grade in early May, with work expected to take four days.
Although the schedule is subject to change, the following is the anticipated order of work. For July: ID-8 from Ruby Creek to Elk River and ID-7 from Orofino to Ahsahka. For August: ID-11 from Greer to the top of the grade and ID-64 from Kamiah to the viewpoint; all areas broomed; then US-95 West South First Street to the concrete section north of Grangeville, US-95 Cottonwood Business Loop, US-95 from Lauer Lane to Westlake, US-95 new passing lane in Culdesac Canyon, US-95 from Lapwai to Spalding, US-12 dike route in Lewiston; all areas broomed. For September: all areas striped.
