The A.J. Acosta Company has been at work on re-opening the Arctic Circle portion of Highway 18, since being hired by CalTrans Monday afternoon to remove snow drifts (some as deep as 30 feet) resulting from avalanches on the morning of February 9. The crew from the Acosta Company worked ’round the clock last night, in hopes of having the roadway open this afternoon. However, large rocks from the hillside, mixed in with the snow, have impeded progress. As of Tuesday afternoon, it was determined that snow removal operations would continue into Tuesday night. The hope is to have Highway 18 west of the Big Bear Dam re-opened on Wednesday morning.
