Officials opened Alligator Alley to traffic about 8:30 a.m. Wednesday after closing the highway overnight due to fog and smoke from an Everglades wildfire, the Florida Highway Patrol said.
The 78-mile stretch of Interstate 75 has been closed numerous times since April 21, when a fire ignited in the Big Cypress National Preserve during a thunderstorm.
The fire, which has burned about 30,000 acres, has been mostly contained by firefighters from around the Southeast. But seasonal fog coupled with smoke from the blaze has reduced visibility enough overnight recently to force officials to close the highway, FHP spokesman Sgt. Mark Wysocky said.
Officials may close the highway again Wednesday night as a precaution, Wysocky said.
