Firefighters continue to battle a wildfire that has burned more than 25,000 acres over the last eight days in South Florida.

The fire, identified as the " 344 Fire ," has affected the only two roads with access to and from the Florida Keys. One of the roads to the Keys remained closed early Friday while officials warn residents and visitors the other road could close again if conditions warrant.

The fire is burning in an area away from commercial and residential development.
