The total length of the Lis River Bridge and viaducts is 924m.
The bridge section is a 220m continuous superstructure comprised of three spans with two parallel prestressed concrete, box girder decks, cast “in-situ” using the balanced cantilever method in 5m segments. The main span has 100m.
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 “in-situ” using the span-by-span method with an under-slug self-launching girder and, in some spans, traditional scaffolding.
The foundations are indirect and reach a maximum depth of 55m. The bridge’s pile/piers have 2.0m diameter piles and the viaduct’s pile/piers 1.5m diameter.
Construction was completed in May 2007.
