Surveillance camera video showed the dog, named Brandi, all alone and ears flopping, bolting up the side of the two-lane span about 10:15 p.m. last Friday.
Several people tried to stop and help but Brandi went over the edge and into the darkness. Bridge police thought she was goner.
Amazingly, Brandi did not break any bones after jumping off the 6-story bridge. She was found on the shore under the bridge with just bruises.
