In 2000, the Lleida City Council organized an open competition for the design of a new pedestrian bridge over the Segre River. Pedelta teamed up with the architecture firm R. Domenech and won the contract. Opened in 2010, the footbridge outstands with sober lines, landscape architectural features and delicate details. It is meant to mark the entrance into the University Campus and achieves a double function: communication and public space.
The best balance of aesthetics, cost and performance in service (vibrations) has been reached through the selection of a four-span configuration: 36.3+49+44.3+33 m with three slender integral piers of reinforced concrete. The deck is composed of a constant-depth steel box girder and a lateral overhang. Abutments are integrated into either existing or new walls, defining a continuity with the built environment of the city. In this way, an integral bridge (without joints at piers) is obtained, in which the deck is fixed elastically and an elegant and slender structure is achieved.
Translucent composite materials (GFRP) have been used in the form of structural floor panels and wall panels for the railings. This high performance structural material requires little maintenance, is lightweight and self-finished, and has been designed to allow backlighting. The structure is designed with double composite action. The steel box girder was assembled on site using temporary supports.
