Abstract:
The Barra Vieja Bridge is situated in Lomas de Chapultepec, south of Acapulco, over the Papagayo River, in the Guerrero state, Mexico. The structure is a bridge of 'concrete sails' with a main span of 220m. The total length of the bridge is 470m, with five spans of 30+40+90+220+90m. The structure was projected without piers in the riverbed as foundations were not feasible due to the liquefaction risks of the ground under the seismic action, which in this zone is very high.
