BRIDGES IN THE NALÓN CORRIDOR

Project details

Technical Data

  • Total length of viaducts: 2279 m
  • Maximum spans: 42 m
  • Width: 13 m

Description

This series of  composite bridges and overpasses in the Nalon Corridor, Asturias, are characterized by their ease and speed of construction.

The cross-section is formed by a Corten-type steel, single cell box girder with double compositeaction at the supports. The deck is formed in  semi-resistant prefabricated slabs and the subsequent  concreting of the remaining section.

The  entire assembly was carried out directly by crane without the need for any type of props or formwork, and always keeping to very tight schedules. This is then the ideal solution for low  viaducts of medium span with short construction periods and where it is necessary to ensure maximum respect for the natural surroundings.
