Ricobayo Arch Bridge

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).
