LOS ALAMOS, Calif. - A vegetation fire sparked in the center divider of Highway 101 near Los Alamos on Thursday.
The fire was reported at around 2:15 p.m.
Heavy smoke and poor visibility forced the shutdown of the highway in all directions while firefighters tried to get the fire under control.
Santa Barbara County Fire spokesman Mike Eliason said it does not seem likely that the fire could jump across the roadway and spread to any nearby vegetation.
By 2:45 p.m., California Highway Patrol was beginning to reopen the roadway to through-traffic.
The fire burned about an acre before firefighters were able to contain it.
