Ukiah road crews are working nights from 8 p.m. to 6 a.m. on the Perkins and Orchard intersection. The noisy work, aided by good weather, involves installing new storm drains to reduce flooding for the Urban Core Rehabilitation and Transportation Project. Southbound Orchard Street will have intermittent closures between Clara and Perkins, though the Pear Tree Shopping Center is still accessible. Drivers should expect delays, watch for workers/pedestrians, and use alternate routes.
