The bridge deck is supported by 4 wood laminated beams, in 3 segments ~20' in length. The 2 main support beams are 7"x12" in girth.  The 2 side beams are 3"x12" in girth. The support beams are founded by 3 concrete piers and 1 concrete buttress, at each 20' intersections of the beam-spans. The 3 piers are comprised of 2 steel-reinforced concrete columns 16" in diameter, rising ~5' from the bottom of the lake tied into a concrete header 22"x12"x12'. The 1 buttress is 22"x12"x12' on the island.
