Update: The slow-going on Highway 101 has resulted in clogged traffic in downtown San Luis Obispo, says Tribune senior photographer David Middlecamp.
He was driving downtown and discovered traffic backed up on Santa Rosa Road from the freeway to Marsh Street. Middlecamp said it was taking two or three cycles of stoplights to get through key intersections like Higuera, Monterey and Palm streets.

Traffic is backed up from the Cuesta Grade all the way into San Luis Obispo, reports Larissa Doust, web producer for SanLuisObispo.com.
According to the CHP highway incident page, one northbound lane of the highway is closed from the summit of the Grade to Tasajara Road.
Motorists are advised to be patient, relax and work through the delay.
