RedactedNarrative: Vessel (FL 3223 PT) was traveling west to east on the south side of the Boca Chica Bridge. The vessel made a sharp left turn near the middle of the bridge to go underneath the bridge. The vessel was hit by the wake of another vessel and collided with the bridge. The two occupants received multiple injuries. 
  
  Operator was operating his vessel along the south side of the bridge; traveling west to east. He stated that he was going to turn under the bridge at the center point. Operator stated that as he made his turn another boat; a 20 foot white center console, drove through the same area he was turning into. A wake was thrown by the other boat and caused Operator to loose control of his boat and be pushed it into the bridge piling. Operator's boat received heavy damage to the front starboard quarter and chine. Upon colliding with the piling Operator was thrown forward into his steering console. He suffered a laceration over his left eye, a neck injury and contusions to both knees. Operator's wife  was kneeling in the boat next to her husband. She was thrown forward and hit the windshield of the boat. She stated that she was kneeling there to observe the track line on the GPS of the boat. She suffered a dislocated right shoulder, a head and neck injury, contusions to both knees, a possible fractured left femur, and multiple lacerations to her head, face, neck, arms, and legs. 
  
  At 1600 hours I interviewed the two "Good Sam's" that assisted with the accident. Good sam1 stated that they were operating their vessel; headed south to pass under the bridge; when they observed a blue boat operating close to the bridge. Good sam1 stated that they were under the bridge when they observed the blue boat make a sharp turn several pilings down from them and collide with the bridge. Good sam1 and her party turned around and rendered assistance until CG and EMS arrived and relieved them. Good sam1 and her party stated that there was no other vessel near the bridge other than theirs at the time of the collision.
