Notes:
- In BFL, Leonhardt described the unusual stiffening approach of this bridge: "An unusual bridge was built in 1955 by B. Birdsall of the firm Roebling, the San Marcos Bridge in El Salvador. The main girders are composed of ropes only. The ropes along the deck are stressed and create a truss action together with the upper suspended ropes and the crossing diagonals. The weight of the deck stiffens the rope truss. The upper cables must be sufficiently high above the deck."
