"La Barqueta" Bridge
, , , , , , , , ,

DESCRIPCION

One of the symbols of the 1992 Seville International Exhibition, Barqueta constitutes an original design for a bowstring steel bridge, a flying central arch rising from the vertex of two lateral triangular frames. The 168 m span over the Guadalquivir River rests in four vertical supports spaced 30 m in the transverse direction.
The pureness of this arch and the clean geometry of the entrance gates, in combination with the welcoming feeling produced in the passers-by as they cross the bridge, the sense of movement and dynamism in the horizontal direction created by the incline hangers, and the explicit expression the flow of forces, results in a bridge endowed with really strong and delicate expressive values, becoming in a milestone in the design of bridges.
The triangular frames receive the corresponding axial force from the arch, avoiding with its opening the occupancy of the deck by the falling arch and, at the same time, constituting true gates for the entrance to the Island where Expo took place. 
The transversal sections of the arch and the inclined feet produce enough local inertia for avoiding any needing of stiffening.
The node which connect the central arch with the inclined feet are the umbilical points of the structure, with intern elements to facilitate  the direct connection between the arch and the feet; while the external appearance  is a clear reflect of its structural mission, from where its expressivity and aesthetical value flows to the rest of the bridge.
