Overnight roadwork is once again being done on Highway 68. Crews are replacing a failed culvert between Quail Ridge Lane and Corral De Tierra Road. A culvert is a drain that carries water under a road, and when it fails the water goes into the ground instead…..and that can cause roads to collapse from underneath. The roadwork on Highway 68 is being done between 7 p.m. and 6 a.m. Monday through Friday.
