Roccaprebalza viaduct – A15 Cisa motorway
A realization at a high altitude
The viaduct, made of a mixed structure with lateral steel beams and upper and lower concrete slabs, has a maximum span between the piers of 125 m.
The construction technique, which SPIC dominates perfectly, has allowed us to operate in a very inaccessible area and with piles up to 105 m high.
The site was managed with two fronts simultaneously, with light work equipments and with reduced loads, operating on spans divided into 14 segments, in addition to the central junction segment.
The speed of construction was remarkably high, considering the intrinsic difficulties of the site, in terms of access and road conditions of the construction site.
