The Ricobayo Dam Arch Bridge is a supported deck arch bridge that carries the National 122 Road over the Ricobayo Reservoir at Esla River, in the province of Zamora, Spain. Its arch is a composite hollow box section of steel and concrete. The total length of the bridge is 219 meters (718.5 ft) with an arch spanning 168 meters (551 ft) and rising 23 meters (75.5 ft) above the maximum water level of the reservoir.

Other impressive bridges on the reservoir: "Requejo viaduct" has a steel arch stretching 120 meters (394 ft) across the Duero River, designed by engineer Jose Eugenio Ribera in 1914, and "Martin Gil Viaduct", measuring 192 meters (630 ft), a world record in its day.

The confusion is that one source says "Martín Gil Viaduct" [Structurae|id=s0002131|title=Martín Gil Viaduct] , Zamora, 209 m was built 1942 and another that "Rio Esla-Brücke" [ [http://www.brueckenweb.de/datenbank/bruecken/brueckenblatt.php?bas=218 www.brueckenweb.de - für den Brückenfan ] ] , Zamora, 192 m was built 1936.
