CalTrans announced today that a culvert failure will result in the closure of Highway 330 and though no specifics were outlined, the roadway could be closed for several weeks. Erosion accelerated by recent storms is cited for the culvert failure, approximately eight miles up the mountain from Highland Avenue. A contractor was hired today (March 15), and emergency work to repair both slope and roadway will commence once material and equipment are readied; still, no start date on this project and the closure of Highway 330 has been identified. During the Highway 330 closure which, again, could last several weeks once the project begins, motorists will be able to access Big Bear Valley using Highway 18 through the desert communities or Highway 38 from Mentone/Redlands; another (longer) option is Highway 18 from San Bernardino through Waterman Canyon and the Lake Arrowhead area to Running Springs, then on to Big Bear continuing on Highway 18 through the Arctic Circle area to the dam.
Update: Per the latest from CalTrans, Highway 330 will be closed as of late Tuesday morning, March 16, and will remain closed for an undetermined amount of time, though likely several weeks.
Revised update as of late Tuesday morning: Downbound lanes on Highway 330 to close as of early afternoon, upbound lanes to close as of 7pm today.
