If you saw a lot of smoke near Airport Boulevard and I-65 interchange around 4:30 p.m., Mobile Fire Rescue Department was battling brush fires on both the Northbound and Southbound lanes. There was also a fire Southbound at the Cottage Hill overpass.
The fires caused a back up in traffic while responders battled the three fires.
Steve Huffman with Mobile Fire Rescue says grass can by dry and brown this time of year and there are several possible causes.
Huffman says often times a discarded cigarette will start a fire or a chain being drug by a car could create sparks.
