US-1 crash with injuries slows traffic in Big Pine Key

Southbound US-1 was blocked at mile marker 30 in Big Pine Key after a crash with injuries was reported around 3:34 p.m., creating an unknown roadblock and slowing traffic through the Lower Keys. Drivers heading between the mainland and the island chain faced delays on the only major road through the Florida Keys, with no immediate estimate for when the blockage would clear.

The Florida Highway Patrol said the crash involved injuries, but released no further details on the number of people hurt or what caused the wreck. Real-time incident reports and road condition updates were being refreshed every five minutes, and FL511 was listing the crash among its live traffic alerts for the area.

Big Pine Key sits at a critical point in the Keys’ transportation network, and mile marker 30 is especially sensitive for emergency response. Monroe County Fire Rescue’s Station 13, Big Pine, is located at 390 Key Deer Boulevard at mile marker 30.5, putting county responders close to the crash scene. Monroe County’s Trauma Star air ambulance service, which has bases in Marathon and Key West and is staffed around the clock, is available for critically injured patients when vehicle crashes require helicopter transport.

The disruption on US-1 carried outsized consequences for residents, workers and visitors moving through the Lower Keys. With no alternate highway through the island chain, a single injury crash can ripple quickly into longer travel times, slower emergency access and backups stretching well beyond Big Pine Key. Florida traffic crash reports can take up to 10 days to become available, leaving the live traffic systems as the fastest source for new details as the scene clears.
