The Carpineto Bridge ( Italian Viadotto Carpineto ) is a motorway bridge in the course of the Raccordo autostradale 5 (Raccordo Sicignano-Potenza) in southern Italy , which connects the A3 from Naples and Salerno with Potenza .

description

The Carpineto bridge consists of two identical cable-stayed bridges for the two directional lanes of the RA 5, which each has two lanes but no hard shoulder. It crosses a hollow in the slope in which the subsoil conditions did not allow any pillars.

The by Riccardo Morandi designed and 1977 finished building is an example of its cable-stayed bridges made of reinforced concrete - pylons and prestressed concrete , to avoid -Fahrbahnträgern in which the stress of one each rope is coated with concrete to vibration and corrosion.

However, the Carpineto Bridge differs from a conventional, double-hipped cable-stayed bridge, in which the bridge deck is supported on both sides of the pylons by the cable tensioning and each pylon is in principle in equilibrium of the cable tension.

The Carpineto Bridge has a single 181 m long opening between the pylons. The 29 m high pylons, which are loaded on one side, are therefore inclined outwards and anchored back in the ground by the external tensions. The approximately 16 m long anchor blocks are supported in the ground by 12 m long horizontal concrete rods against the pylon foundations.

For his Viadotto Ansa del Tevere, completed in 1967 on the A91 autostrada from Rome to Rome-Fiumicino Airport , the designer had already implemented the construction with just one pylon and therefore one-sided back anchoring. At the Carpineto Bridge, there are two pylons opposite each other, each supporting a T- beam protruding 69.5 m into the opening . The remaining space is closed like a Gerber girder bridge by a 42 m long suspension girder .
