Pushed bridges, in Mexico

A series of road and railroad pushed bridges have been built by using the same equipment which was made for other bridges some years ago and it has been reused many times. Since seismic intensity is very high for all of them, it has been found necessary to anchor the decks to one of the abutments. The connection of the abutments to the ground is made by prestressed anchorages or by means of the prefabrication workshop which is left buried and connected to the abutment. The Tula river, the Antoyac-Chiquihuite and the San Juan river bridges, all of them with 52 m long spans, have been built for the mexican railroad company. The Badiraguato river bridge, with 48 m long span, the Marquesa bridge, with curved shape and 60 m long spans, and the Atenquiques bridges over the Tuxpan river, with 60 m long spans, have been built for the federal highways.
