It is a 378.50 m long continuous bridge consisting of four 64.25 m +125 m+125 m+125 m+ 64.25 m spans.<\/p>\n

The piles are made of reinforced concrete with heights of 18, 33 and 37 meters.<\/p>\n

The lintel, mixed, has a width of 30 m, and a constant edge of 6.50 m.<\/p>\n

The cross section consists of a 10 m wide central box and 10 m wide cross cantilevers.<\/p>\n

The support of these cantilevers is provided by a triangulated bracing that constitutes two new lateral cells that help the central box in its torsional work.<\/p>\n

In this bridge, an exhaustive calculation of the nonlinear behavior of the steel box girder and the long-term behavior of the interaction between the concrete slab and the steel girder was carried out. The concrete slab is prestressed. <\/p>\n

Construction was carried out in two ways. All the spans, except for the one on the left bank and half of the 125 m span next to it, were erected on derricks; the rest, due to the inaccessibility of an extraordinarily steep slope and the fact that the estuary has permanent water on that side, were built by pushing. But this operation presented a particularity. <\/p>\n

The thrust had to be higher than the final location of the caisson, because the excavation of the caisson edge into the ground endangered the stability of the hillside.<\/p>\n

Once, during the thrust, the front of the lintel reached the pile higher than it should have, the board was rotated from the stirrup until the tip of the lintel rested on the pile and from then on the thrust became inclined.<\/p>\n

Once the thrust was completed, the end of the lintel was hung on the abutment from a special gantry and the previous turn was undone, leaving the bridge in its final position.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
