On Tuesday, the fire closed down Florida's famed 18-Mile Stretch, a section of US-1 linking southern Florida to the Keys, along with Card Sound Road. Miami-Dale Fire Rescue said it was responding to the incident and that no casualties had been reported as of shortly before 5 p.m. on Tuesday.

Travelers were stuck in gridlock traffic jams after authorities closed the only two roads in or out of the Florida Keys due to a brush fire.

Fire and law enforcement officials, with assistance from the Florida Highway Patrol, have blocked both routes while crews work to contain the blaze.
