The La Dept of Highways built the bridge (I believe). My father,Paul J Mayne, was one of the civil engineers in charge of the work. We would drive over it and he was very proud of how level the concrete supports were after so many years in a swamp.
Funny story, my mother used to bring him lunch occasionally and on e she noticed a framed sawing off a board upon which he was sitting. But he was sitting on the part of the board that would fall into the water. My mom said “Paul , you going to let that man saw himself off into the water?” He said “ Yeah, he won’t do it again!”
