A brush fire that burned near Old Town San Diego Wednesday night has been knocked down, authorities confirmed.
Fire officials said the blaze – which burned in trees and vegetation – sparked around 6 p.m. on Morena Boulevard, near Interstate 5. By 6:15 p.m., the fire had burned approximately half an acre.
Firefighters were able to knock it out by 7:15 p.m., holding the blaze to that half-acre mark. Officials said the fire proved difficult to tackle due to the heavy brush in the riverbed where it sparked.
While crews worked to contain the blaze, officials shut down Morena Boulevard off-ramp on westbound Interstate 8. Taylor Street was also temporarily blocked off.
As of 7:15 p.m., officials expected Morena Boulevard to remain closed for at least another hour.
Given the recent dry, windy weather, San Diego has been under a red flag warning for increased fire conditions this week. A wind advisory remains in effect in the county through 2 p.m. Thursday.
The cause of the fire is under investigation. Check back for updates on this developing story.
