About The Bridge

The Papaloapan Bridge is a stay cable bridge that crosses over the Papaloapan River in Veracruz Mexico and was built in 1995. The bridge is 1325 feet, 666 feet at its longest span, and 75.5 feet wide. The bridge contains 112 cables. The columns on the bridge are solid concrete rather than hollow and do not have any cross beams. This allowed the crane to rotate a full 360 degrees during construction.
