A massive wildfire in the Florida Everglades has burned nearly 30,000 acres of a national preserve, but the major roadway known as Alligator Alley will stay open unless smoky conditions worsen.

The Florida Highway Patrol said the road connecting the state's East and West coasts and Broward and Collier counties will be open Wednesday. State Road 29 remains closed.

Fire officials say the blaze has burned 27,000 acres in the Big Cypress National Preserve.

The fire is 60 percent contained.

Alligator Alley has been intermittently inaccessible since last week because of the fire, which was likely sparked by a lightning storm. Dry conditions have fueled the flames.

Motorists are advised to continue using alternate routes at night because of poor visibility.
