Sonoma County’s roads department plans some projects this week that likely will cause traffic delays:

–Mirabel Road, 7:30 a.m. to 4 p.m. Tuesday through Thursday, crews will grind out damaged sections of the road between Nolan and River roads and then repave them. One-way-traffic control will be in effect. This is a continuation of a project start last week.

–Porter Creek Road, 8 a.m. to 4 p.m. Tuesday through Thursday, crews will repave a stretch of the road west of Petrified Forest Road. One-way traffic control will be in effect.

–St. Helena and Valley Ford-Freestone roads, Tuesday and Wednesday, Cal Fire crews to clear roadside brush.
