The ‘Y’ Bridge is located within the Madrid Río area, which has consisted of the development and urbanisation of six kilometres around the banks of the Manzanares River in the city of Madrid, constructing a natural landscape on the banks of the river that uses the valuable landscapes of the north of the city as a reference point.

The ‘Y’ Bridge is built with lattice girders formed by a very dense lattice of steel profiles that completely envelop the deck, generating a formidable interior space. Moreover, the geometry of these trusses, with a "Y" shape and pointed on the ground plan, and truncated conical in elevation, with a height of between 2.40 and 4.50 m, in each of its three arms, produces a dynamic and visually rich space.

The western arm, on the right bank, and the northeastern arm, on the left bank, constitute the main trunk of the bridge, with a length of 69 m and a span of 63.35 m. At the point where the three arms meet, it opens onto the river with a large gap in the truss, where the lattice of profiles defining the vertical faces is interrupted to offer the walker or cyclist a unique perspective of the riverbed. The bridge has a further opening on the west side of the south arm, halfway along its length, and a viewing balcony on the northeast arm, which juts out from the main arm of the bridge and affords unprecedented views of the bridge itself.

The main chords of the trusses are profiles formed by welded steel plates and the truss is completed with a framework of diagonal bars in all the planes that form each of the arms of the bridge. On the lower chords an auxiliary structure, formed by double T-profiles, builds the deck support on which galvanised steel tube battens rest. The paving is formed by wooden planks that produce a continuous and broken plane that emphasises the special character of the bridge.
