The viaduct, a continuation of the Talavera cable-stayed bridge, crosses the Molino Island and the small left channel of the Tagus River, within the route of the Ring Road of the city. The viaduct is 408 meters long, with two extreme spans of 36.00 meters and seven central spans of 48.00 m.
It has a plan layout that begins in a straight line and ends in a curve of radius 650 m, including an intermediate clotoid. Due to the vast width of the cable-stayed deck, two twin bridges, each 16.50 m wide, have been chosen for the access viaduct, leaving a gap between the decks of 3.00 m that make up the median. Each deck with a width of 16.50 m, has a carriageway of 11.00 m, with an internal shoulder of 1.50 m, two lanes of 3.50 m and an outer shoulder of 2.50 m, the pedestrian zone is left with a width of 4.50 m.
The bridges are made of continuous white prestressed concrete with a constant depth of 2,575 m, with a hollow box section in the central core, with two sloping trusses and lateral cantilevers of 3.15 m to the core.
The bridges are longitudinally prestressed with parabolic tracing employing 12 31-cord 0.60” tendons; this prestressing is conditioned by keeping the entire bridge compressed for frequent loads.
There are 9 intermediate piles; they are white reinforced concrete trapezoidal piles with a thickness of 1.60 m and a treatment of grooves in their finish.
