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.
