The 15 Freeway reopened Wednesday afternoon after a 50-acre brush fire in the Cajon Pass forced officials to block it.
The fire erupted around 11 a.m. near Kenwood Avenue and and Cajon Boulevard, according to the San Bernardino County Fire Department. It was 50 percent contained as of 8:15 p.m., according to the federal information website InciWeb. An evacuation advisory for Mathews Ranch and structures north of the blaze was also lifted.
Smoke from the blaze affected the highway in the area. Aerial video from Sky5 showed traffic was backed up for miles as the smoke dissipated.
Smoke may continue to be visible later Wednesday as occasional flare ups occur, fire officials said.
At 2:41 p.m., Caltrans said the 15 Freeway has been reopened in both directions, but later clarified that the two right southbound lanes remained closed. The 215 was also cleared.
Old Cajon Boulevard between Cleghorn Road and Kenwood Avenue remained shut down as firefighters continued work in the area.
Some 250 personnel were assigned to the incident, InciWeb said.
