The total length of the Lis River Bridge and viaducts is 924m.<\/p>\n
The bridge section is a 220m continuous superstructure comprised of three spans with two parallel prestressed concrete, box girder decks, cast \u201cin-situ\u201d using the balanced cantilever method in 5m segments. The main span has 100m.<\/p>\n
The access viaducts, with a total length of 516m and 188m for the eastern and western viaducts respectively, have two parallel decks constituted by a continuous open girder cast \u201cin-situ\u201d using the span-by-span method with an under-slug self-launching girder and, in some spans, traditional scaffolding.<\/p>\n
The foundations are indirect and reach a maximum depth of 55m. The bridge\u2019s pile\/piers have 2.0m diameter piles and the viaduct\u2019s pile\/piers 1.5m diameter.<\/p>\n
Construction was completed in May
