Crews respond to a gas leak at a Chevron station on Alton Road in Miami Beach.
Miami Beach Fire Rescue and Hazmat crews responded to reports of a large gas leak at a Chevron station early Thursday morning.
Around 1,000 gallons of gas leaked from a pump at Larry's Chevron at 1800 Alton Road around 5 a.m.
It's unknown how the leak began but authorities say an employee smelled the gas and tried to shut the pump down.
Miami Beach Fire Chief Javier Otero said gas was spewing from air release pipes on the roof of the station.
"It was coming out about two feet above the pipes," Otero said. "Normally it should be releasing air, not gas."
The leak caused Alton Road to be shut down between Dade Boulevard and 20th Street. Alton Road was later reopened but West Avenue between Dade Boulevard and 20th Street remained closed.
The leak was contained around 5:15 a.m. and crews were working to clean up the gas spill.
