Devoll Bridges

Following the construction of the dam on the Devoll river and the raising of the waters in the basin, it was necessary to raise the share of the existing road and consequently the construction of various bridges to overcome the waterways that intersect with the road layout. The project comprises 55 km of roads and is divided into 3 sections: Sec.3A, Sec. 3B, Sec. 1. The project comprises 15 bridges with reinforced concrete piers and abutments with pile foundations. Decks are seismically isolated from the substructures using specific devices connected transversely to the substructures themselves and longitudinally to an anchor block realized behind one of the abutments. The decks are of two types: n.8 with steel-concrete composite sections (single-span and multi-span) and n.7 with prestressed concrete beams (pinned-pinned multi-span with kinematic chain).
