The California Highway Patrol shut down northbound I-5 at Halsey Canyon and advised drivers to use the westbound SR 126 to the 101 Freeway as an alternate.
About 4:00 p.m., a brush fire broke out in LA's Sepulveda Basin at Woodley Ave, northwest of the 405/101 junction. The fire burned 30 acres and was 20% contained by 6:20 p.m.
There was no immediate threat to structures from the Basin Fire, Los Angeles Fire Department officials said. Homeless people living in the area were evacuated south. Residents of Sherman Oaks and Encino were warned to gather belongings should they need to evacuate.
The causes of the three significant fires were not immediately determined.
