The Ricobayo Arch Bridge (Spanish: ''Puente de San Esteban'' or ''Arco de Ricobayo'') is a supported deck arch bridge that carries the
National 122 Road over the
Esla River at
Ricobayo in the province of
Zamora, Spain.
The original bridge at Ricobayo was drowned after the river was dammed impounding the Ricobayo reservoir. The arch bridge rises 23 m (75.5 ft) above the maximum water level of the reservoir.
Its arch is a composite hollow box section of steel and concrete. The total length of the bridge is 219 m (718.5 ft) with an arch spanning 168 m (551 ft).
