Highway 101 was partially shut down north of Buellton on Friday afternoon due to a two-alarm vegetation fire burning in the area.
Santa Barbara County firefighters were dispatched at about 12:45 p.m. to the fire burning in the center median.
The flames jumped to the northbound side, and had expanded to about 10 acres shortly after 1 p.m., according to Mike Eliason, a Fire Department spokesman.
Helicopters and fixed-wing aircraft were requested to assist in battling the blaze, and a second alarm was issued.
Shortly after 1:30 p.m., the fixed-winged aircraft were canceled after the forward progress of the flames was stopped at about 15 acres, Eliason said.
The northbound highway lanes were shut down at Highway 154, Eliason said.
A pilot car began escorting vehicles through the area shortly before 2 p.m., but an hour later, the northbound highway remained closed.
