Part of a freeway interchange near San Bernardino was shuttered for about an hour Friday afternoon due to a brush fire.
Caltrans officials said just before 4 p.m. on Twitter that the westbound 10 Freeway to the northbound 215 Freeway was closed.
"Low visibility and traffic is beginning to back up," the agency said.
An hour later, Caltrans tweeted that the interchange had been reopened.
No other details on the fire were immediately available.
