A brush fire closed lanes on the 15 Freeway in the Cajon Pass Tuesday between Southern California and Las Vegas.
The Blue Fire was burning near Cleghorn Road in the pass between the San Bernardino Mountains and the San Gabriel Mountains.
Two lanes on the northbound 15 Freeway were closed as firefighters attacked the fire, estimated at about 10 acres. Caltrans reported significant delays at midday.
The fire's forward spread was stopped, but lane closures are likely to continue into the evening.
No structures are threatened. No injuries have been reported.
