The Sori Viaduct ( Italian Viadotto sul torrente Sori ) stands east of Genoa on the Autostrada A12 ( Autostrada Azzurra ) above the village of Sori , where it spans the Torrente of the same name at a height of 125 m.
description
The Sori Viaduct has two lanes in each direction, an approx. 1.20 m wide emergency lane and massive concrete guide walls in the middle and at the edges .
The 393 m long bridge has six openings with pillar spacing of 30.78 + 31.56 + 65.73 + 100.00 + 100.00 + 65.00 m. The superstructure of the main bridge consists of a haunched , in cross-section rectangular 13,50 broad prestressed - hollow box , which protrudes on both sides of the three pillars 35 m. The remaining gaps are closed by 30 m long T- beams. The carriageway slab protruding 2.60 m on both sides is 19.10 m wide.
The three reinforced concrete pillars are 6.0 m wide. At 13.50 m across the roadway, they are the same size as the box girder.
A T- beam bridge with 2 fields and 1.9 m wide pillars connects to the main bridge in the west .
The bridge was designed by Silvano Zorzi and Sergio Tolaccia . The bridge was opened to traffic together with the Genoa - Rapallo motorway section on December 18, 1967.
The Nervi Viaduct , also planned by Silvano Zorzi, is located further to the west in this section and is structurally identical to the Sori Viaduct, apart from differences in the length of the T-beam bridges and the height of the piers due to the terrain.
With the two bridges, Silvano Zorzi first introduced the Dywidag system of cantilever structures in Italy.
