This bridge has an interesting structure. Four parabolic-shaped members descend at midspan to support the deck and then ascend to form triangles with diagonal elements at the supports. There is also a bottom chord along the sides of the deck that ascends slightly at midspan. The diagonals and the bottom chord are in compression and the parabolic elements are in tension. I think the structure is a kind of truss, although it also reminds me of a suspension bridge with it's parabolic shape. We'll take another look at this interesting structure tomorrow.
