Highway 18 had been closed at the Big Bear Dam yesterday evening, after an unanticipated volume of rock fell during a blasting excavation for the Big Bear bridge project. CalTrans crews closed Highway 18 for cleanup and safety evaluations, which resulted in the closure of the roadway until after midnight. The road is open at this time [morning, November 11], though motorists can expect delays, despite the Veterans Day holiday, as the pavement rehabilitation project continues, from Lakeview Point on Arctic Circle to the Highway 330 junction in Running Springs. Those taking Highway 18 the front way can expect delays up to 20 minutes through the Snow Valley area, as traffic will be escorted by pilot car. There is no roadwork planned for Highway 38 or Highway 18 toward the desert communities this week, so those routes should be free of delays.
