The viaduct, 492 m long, consists of 13 spans of 37 m in length. Its width is 22 m, accommodating two lanes in the direction of Oviedo (downhill) and 3 lanes in the direction of León (uphill). The structure, designed by CARLOS FERNÁNDEZ CASADO S.L, is completely prefabricated, constituting a unique and innovative example at the time of construction: prestressed beam deck and upper slab executed on pre-slabs, supported by reinforced concrete piers. The bridge was built between 1981 and 1982.
