California's cold snap is expected to last throughout the weekend.
SAN DIEGO — California authorities have reopened a 40-mile stretch of a major highway north of Los Angeles, some 17 hours after snow shut the route and forced hundreds of truckers to spend the night in their rigs.
The California Highway Patrol shut down the Interstate 5 segment Thursday afternoon. Officers began escorting traffic southbound Friday morning and then opened northbound lanes about an hour later.
The 4,100-foot-high pass is a major north-south trucking route, but it's frequently closed in winter because of blinding snow and black ice.
Meanwhile, farmers around the state are trying to protect their crops from a cold snap that sent overnight temperatures plunging into the 20s and 30s in many areas. The frosty weather will continue through the weekend.
