Strategic junctions for ordinary traffic flow
The construction of two new bridges in the Valle Seriana was necessary following the landslide of 15 June 2001. This calamitous event has obstructed the S.P. n. 27 of the Seriana Valley at km. 22 + 400 for a stretch of about one hundred meters, causing considerable disruption to the road network of an entire valley that includes the municipalities of Bracca, Algua, Costa Serina, Serina, Oltre il Colle, Aviatico and Selvino.
The works performed can be summarily summarized as follows:
– new variant formation with the construction of n. 2 bridges in mixed structure iron and C.A. ;
– a section of the connection between the two bridges on the road;
– formation of rock rocks in regimation of the riverbed.
The total length of the variant is about 370.00 metres. The two bridges, identical in length and typology, are made of a mixed steel-concrete system with a static pattern of beams simply supported by light. 45.00. Atmospheric corrosion resistant steels have been used for obvious maintenance reasons, in particular COR-TEN grade steel which is of the self-oxidizing type.
