COLLIER COUNTY, Fla. — A large brush fire continued burning inland in Collier County on Wednesday, sending thick smoke across nearby roadways and toward Alligator Alley as dry conditions made containment difficult. While flames were no longer visible from the main road, the fire continued to burn deeper in the brush, with wind pushing heavy plumes of smoke across the region. The fire has burned at least 24,000 acres, according to the National Park Service.
