Authorities are on scene of a vehicle crash with injuries on the Howard Frankland Bridge that has blocked the northbound lanes of traffic on the Tampa side.
Preliminary information indicates that a 60-year-old man driving a small pickup truck rear-ended a semi hauling a boat, said Lt. Joel Granata of St. Petersburg Fire and Rescue.
"He hit the back of that and was entrapped," Granata said.
Fire rescue crews had to extricate the man from his truck.
A Bayflite helicopter landed on the bridge to airlift the man, who has not yet been identified. He is being taken to Tampa General Hospital as a trauma alert, Granata said.
The semi's driver was not hurt. Lanes should reopen soon, officials said.
Florida Highway Patrol is investigating.
