Investigators said the motorcyclist was traveling north on Staff Sgt. Macario Garcia Drive at Avenue W when he went out of his lane.
According to officials, it doesn't appear the biker was speeding, but he lost control and hit a concrete barricade, sending him flying off the bridge and falling more than 40 feet.
Officers said the man was wearing a helmet, but it didn't make a difference in this crash. He was killed instantly.
His name has not been released.
