In addition to the elevated walkway, the Alamillo Bridge features a lookout at the top of the inclined tower, accessible by a stairway enclosed within the tower.

inclined backward, counterbalancing a 200 m span with thirteen pairs of cables. Since the weight of the tower is made to be sufficient to counter-balance the deck, back stays are thus not required, effectively substituting the weight of an inclined tower for one set of stay cables. In this way, a new type of

The bridge deck consists of a hexagonal steel-box-beam spine to which the stay cables are attached. Side steel wings cantilevered off the hexagonal spine support the traffic decks, three lanes on each side. The top of the hexagonal spine, elevated 1.6 metres (5 feet) above the road level, serves as

While the
Alamillo Bridge is dramatic and widely acclaimed aesthetically, an analysis of its structural engineering show that it has an inefficient dynamic structural form because of the lack of backstays or anchorage to provide a restoring force under changing loads. One indication of this is the

The static concept of the bridge can be traced back to the 1986 sculpture by
Calatrava entitled 'Running Torso', in which inclined stacked marble cubes are balanced by a tensioned wire. The Alamillo Bridge consists of a single straight steel-shell tower, infilled with reinforced concrete and

The
Alamillo Bridge is the first cable-stayed bridge that is balanced solely through the weight of the massive tower, not requiring any type of back stays or anchorage. There are 54 steel piles under the bridge, acting passively under the tower. Calatrava's

The original intent was to build two symmetrical bridges on either side of the island, but in the end the
Alamillo's singular asymmetric design has proved most striking.
