COLLIER COUNTY, Fla - A 20,000 acre fire in the Big Cypress National Preserve remains 40 percent contained late Monday night.
The fire has been burning along I 75 for three days.
Early Monday Florida Highway Patrol shut down an 80 mile stretch of Alligator Alley between mile marker 101 in Collier County and mile marker 23 in Broward County. FHP officials say at points the visibility was less than 150 feet.
Late Monday, the smoke cleared and the highway re-opened, but officials say any shift in wind direction could cause the roads to close again.
Park ranger Ryan Stubblebine says, "any wind in the area could fuel the fire into any direction so that's what we like to keep an eye on."
