It is a bridge built over one of the main access and exit routes to Madrid, the A-6 Madrid - La Coruña highway, with high traffic intensity, which shouldn’t be disturbed during the execution of the bridge.
It is formed by two lateral concrete cells built on falsework and a central part with two lateral steel arches and deck edge ribs located below them with a steel-concrete composite section.
Statically, the structure composes an arch bridge with plastic joints at its bases. It starts with a solid concrete strut that connects to the deck and takes the form of a pedestal once is over it, offering the steel the final support surface from which the arch will start.
The vertical stays, rhythmically spaced 5 m, are made up of steel profiles, which, like pieces embedded in the raised arch, are born from the deep grooves of the underside of the arch.
In addition to its clear and clean construction system, this bridge gives an elegant image in one of the main entrances to Madrid, where its white and slender arches act as a truly access gate to the city.
It is interesting also due to the shapes of the side cells, with their robust and profiled struts, the prestressed cross beams that link the deck edge beams, and the nabla-shaped cross beam that connects the heads of the concrete struts.
Elevated steel arches rise from the concrete pedestals and separate the pedestrian walkways from the traffic lanes.
