The lintel is continuous throughout the entire viaduct, 905 m long with joints in abutments, and is formed by a central concrete box and transverse cantilevers with variable-edged slabs supported by precast concrete struts, placed every 4.3 meters.
The Navia Viaduct has been distinguished by the jury with a Special Mention in the category of Civil Engineering Structures, in the 2010 fib Awards for Outstanding Structures.
