All lanes on State Route 78 have been reopened after a brush fire, fire officials said.
A Sig alert had previously been issued for the brush fire, which closed down two lanes of the highway.
The fire started around 1:30 p.m. Sunday at state route 78 near San Marcos, approaching Sycamore Avenue between Rancho Santa Fe road and Sycamore Avenue.
The brush fire was on the right shoulder and fire crews were blocking two right lanes as they worked to put it out.
Cal FIre and the California Highway Patrol responded.
