Santiago urban underground railway viaduct, “Line 4” - 2004

Within the framework of the extension to the Santiago urban underground railway (33 km of new lines), VSL, a Bouygues Construction subsidiary specialised in prestressed systems and bracing systems for large bridges, was subcontracted by a group of Chilean contractors to build a 7,200 m long viaduct using prefabricated segments. The result is a viaduct comprising 2,222 segments, each weighing 40 tonnes, built to allow the new line to cross the Chilean capital from north to south.
