A large marina fire in Marathon early Monday morning forced deputies to close a stretch of the Overseas Highway in both directions.
Monroe County Sheriff's Office spokeswoman Becky Herrin said the fire at mile marker 47.5 started about 2:30 a.m.
Florida Keys firefighters were called to a boat fire, but when they arrived, they found that the flames had engulfed a house and about an acre-sized lot filled with wooden lobster traps.
One home was evacuated while firefighters battled the flames.
The fire was contained about 5:30 a.m.
Marathon Fire Rescue Chief John Johnson said nobody was injured.
Monroe County spokeswoman Cammy Clark said U.S. Highway 1 was closed so that firefighters could connect fire hoses to water supplies on the other side of the highway.
The cause of the fire remains under investigation.
