Detalhes

The pedestrian bridge is located on the marginal avenue, in Algés and allows the crossing of the rail-road routes that separates the area of Algés from the Port area.

In plan, the bridge is built according to a "T" which starts with the ramps on the north with a total of about 120 m, while the south side, the ways of movement is separated between the stairs and the access to the ramp area with a total length of about 120 m.

The pedestrian bridge consists of a continuous board in its total length of 98 m. This length is divided into four spans. The northern extreme has a cantilever of 6 m defining the four intermediate a modeling of 24, 20, 24 and 24 m, between the support axles.

In longitudinal profile, the bridge is built on two straight spans that, for aesthetic reasons, were built in a fully horizontal span with 24 m of length.

Transversally, the bridge has a width of 3.10 m between the limits of the outer guard, each with 0.30 m wide, thus defining a useful platform with 2.50 m wide, where it will be possible to accommodate two pedestrian routes, which are also made for disabled people and users with a bicycle or in-line skates.

The cross section is in U, which consists of longitudinal full-bore beams located on both sides of way of movement, linked in the inferior part by cross bars arranged transversely and by the slab where the pavement is supported. This slab of metal sheet of lost shuttering over concrete cooperates with the resistance of the slab. The cross section is reinforced by reversed rigidity gateways, away from one another, 1.50 m.

The pillars are steel-concrete mixed made with metal profiles of CHS round-type filled with reinforced concrete. The piers, given its considerable flexibility, are connected to the board and ensure the compatibility of longitudinal and transversal displacements. The work is lengthwise rag-bolt, to the access ramps structure, on the south side.
