Architect(s) : José Luis Manzanares

The El Cachorro (de Chapina) bridge consists of two parallel orthotropic steel arches, each 7 metres wide.
Each arch is made up of a tri-cellular section box, the height of which varies between 2.15 and 2.50 metres.

A 220-metre long deck is supported by the arches through a metal structure. It weighs 530 kg per square metre, bringing the total weight of the building to 3500 tonnes.

The arches are hollow and contain electrical cables, telecommunication cables and other pipes.

The roadway is curved in the middle to drain off rainwater on the side.

The bridge has 6 lanes and pavements with a width of 5.5 metres.

The bridge has a minimal visual impact due to its slenderness and harmonious integration into the landscape.
