A US truck driver has had a miraculous escape after losing control of his semi-trailer and nearly nose-diving into water below a Florida bridge.

Vision shows the cabin of the truck jack-knifed with its trailer and dangling perilously over the edge of the Gulf Coast bridge.

It is understood the driver lost control of the truck and crashed through the railing of the bridge after another vehicle changed lanes in front of him on Friday.

The man managed to escape from the truck, seemingly from the driverís door.

Traffic were stopped on one side of the bridge.

A crane was needed to lift the cab back on to the bridge.
