Bridge over M-11 road

The structure is located on a curved alignment of 597.64 m radius. The length is 92.00 m, distributed in 25-42-25 m spams.

The bridge is a composite structure with constant depth. The deck, with 12.40 m width, consists of a concrete slab with a variable depth from 0.20 to 0.35 m in cantilevers, and from0.35 to 0.25m in the steel box girder, situated in the central zone. The slab was concreted on precost concrete slabs, with same width as the deck.

The steel box girder consists of a lower plate of 3.00 m wide, two lateral inclined cores, crowned with upper platbands of 0.70 m wide, which are used as a connection to the concrete slab.

Two piers were arranged with variable section, which changes with height. This section is perceptibly rectangular with steel plates in the central zone. The abutments are made of reinforced concrete.
