The firefighter, identified as 40-year-old William Scott Tanksley, was among emergency crews assisting a motorist in Southwest Dallas on a flyover from eastbound Interstate 20 to Spur 408.
Initial reports indicated a passing car slid on the ice and struck Tanksley, forcing him over the side of the bridge and onto an overpass below.
"A lot of people got out of their cars," said witness Antuanette Parram. "He was just laying there."
Parram said the fireman — in uniform but not wearing a helmet — was face down and unresponsive.
"There was nothing we could do," Parram said.
Fellow rescuers initially called for a CareFlite air ambulance, but weather conditions were too poor to fly. Tanksley was rushed by ground ambulance to Methodist Central Hospital in Dallas where he was pronounced dead upon arrival, according to Dallas Fire-Rescue.
