On Saturday morning, a semi-truck accident resulted in over 120 gallons of fuel spilling onto the Dolphin Expressway, prompting the closure of westbound lanes in Miami-Dade County, Florida, as confirmed by Miami Fire Rescue (MFR) officials.
Rescue teams were alerted to the incident shortly after 8:30 a.m. and quickly mobilized to the scene, according to the agency.
They immediately deployed their hazardous materials unit to manage the spill and prevent the fuel from further spreading across the roadway.
"MFR teams responded promptly after 8:30 a.m. and activated their hazmat team to contain the spill and prevent additional runoff," authorities specified, as reported by Local10 news.
Officials cautioned that the affected lanes would remain closed for several hours while crews worked to clear the spilled fuel and remove the crashed truck from the road.
The exact location of the incident on the expressway and the precise number of lanes blocked were not disclosed.
Fortunately, no injuries were reported as a result of the accident, which was the sole positive aspect of an incident that caused considerable traffic disruptions on one of South Florida's busiest highways.
Significance of the Dolphin Expressway
The Dolphin Expressway (SR 836) spans approximately 15.3 miles, serving as the primary east-west corridor in Miami-Dade County. It links western suburbs such as Tamiami and Sweetwater with Miami International Airport, downtown, and I-95, and connects to I-395 towards Miami Beach via the MacArthur Causeway. Even a partial closure significantly impacts traffic flow across the metropolitan area.
Recurring Highway Fuel Spills
Fuel spills on Miami-Dade highways have become increasingly common in recent months. In January, a fatal accident on the same expressway led to the closure of westbound lanes near NW 57th Avenue, with the Florida Highway Patrol leading the investigation.
In April, an overturned semi-truck on the Florida Turnpike in Broward County spilled over 50 gallons of fuel, causing similar closures for hours. In February 2025, a tanker truck in Miami lost gasoline on a highway, creating a comparable scenario with blocked lanes and hazmat teams at work.
Such incidents trigger response protocols from Miami Fire Rescue, the county's fire and rescue agency responsible for managing hazardous material spills on highways to prevent environmental and road safety hazards.
As of this report's publication, cleanup operations were still underway, and no timeline was provided for the full reopening of all lanes.
