The Navia Viaduct, constructed by FCC, has been distinguished by the jury with a Special Mention in the category of Civil Engineering Structures at the 2010 fib Awards for Outstanding Structures.

The results of the call for entries will be presented officially on 29 May 2010 at the Third Congress of the International Federation for Structural Concrete, which will take place in Washington.

Navia Viaduct is a bridge of great beauty that forms part of the relief road of the same name. It has seven spans, measuring 46.3 + 70.0 + 3x75.0 + 2x160 + 75.0 + 67.5 + 60.0 + 41.5 metres. The main spans are each upheld by a composite arch inclined four degrees toward the inside of the curve and lying on the medial line.

The 905-metre-long cross beam is continuous over the entire viaduct. It has joints at the abutments and is made of a central concrete box girder and transverse cantilevers with a slab of varying depths held up by precast concrete braces set every 4.3 metres.
