Fire crews are battling a massive brush fire known as the 344 Fire, which has burned 24,000 acres in Monroe County and remains only 30% contained.
The blaze has forced the closure of Card Sound Road and officials warn that U.S. 1’s 18-Mile Stretch could face intermittent shutdowns in the coming days.
Authorities urge travelers to prepare for heavy delays and avoid the area if possible.
Fire containment efforts ongoing
Miami-Dade Fire Rescue and the Florida Forest Service are leading the response, with additional water tankers set to arrive on Friday.
Firefighters are facing difficult conditions due to low humidity and gusting winds, increasing the risk of further spread.
Officials emphasize that drones must not be flown in the area, as they can disrupt crucial aerial firefighting operations.
Traffic and travel impacts
While U.S. 1 remains open, closures may be necessary to assist firefighting efforts.
Monroe County Emergency Management advises motorists to expect lengthy stops and detours.
So far, emergency services in the Florida Keys remain unaffected.
Residents and travelers can stay updated on road conditions through the Monroe County Sheriff’s Office app, social media, and FL511.com.
Officials urge the public to avoid outdoor burning, discard cigarettes safely and ensure trailer chains do not drag, as fire risks remain high.
