The International Federation for Structural Concrete singled out Navia Viaduct for a special mention in the "Civil Engineering Structures" category of the federation's 2010 awards. The fib Awards for Outstanding Structures were conferred on the foremost concrete structures finished between 2006 and 2009.

The ceremony took place on 30 May last in Washington, DC, during the opening of the third fib congress. Michael Fardis, president of fib, presented the award-winning projects and handed out the award diplomas.

The diploma for Navia Viaduct was collected by José Ignacio González Esteban, manager of FCC Construcción's Structure Service, in his capacity as project manager.

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.
