MARATHON, Fla. -

Salty’s Waterfront Grill in Marathon was destroyed by a fire early Saturday morning.

Monroe County Sheriff s Office said the fire broke out at around 3:00 a.m. Seven fire trucks responded to the scene to find the property fully engulfed by the fire.

A car in the parking lot of the restaurant and two boats at the Seven Mile Marina were also scorched by the flames.

MCSO deputies immediately stopped north and southbound traffic on US 1. Meanwhile, Florida’s Fish and Wildlife Conservation Commission kept a close eye on boats in the water which had broken free from their moorings.

It took fire crews several hours to completely douse the flames and put out the hotspots.

The cause of the fire is under investigation.
