The dog got away from its owner during a walk along the Burlington Riverfront Promenade Friday night.
Bridge officer Rob Bittner saw Brandi walking up the Burlington-Bristol Bridge toward Pennsylvania.
Bittner tells The Courier-Post of Cherry Hill he turned on his emergency lights to slow traffic and followed the dog. Bittner says Brandi was doing fine until she got to the top of the span and her paws felt a steel grate.
The officer says Brandi jumped into the Delaware River as motorists tried to grab her.
The beagle's owner recovered her and took her to a veterinarian. Brandi was bruised around the abdomen, but didn't have any broken bones.
