Officials said a boat on the Alafia River hit a pylon of Interstate 75 about 9:45 p.m. The accident left two injured people in the water. Part of I-75 was temporarily shut down so a rescue helicopter could take one of the injured boaters to a hospital. The other victim was transported by ambulance. Officials from the Hillsborough Sheriff's Office, county Fire Rescue and Florida Fish and Wildlife Conservation Commission worked the case.
