This viaduct rises over the river Molinar and connects the town centre with the quarter of the Viaduct and with the Callosa d’En Sarrià road. It was designed by the engineer Próspero Lafarga. Enrique Vilaplana Julià, an engineer from Alcoi, also took part in its construction.
The Viaduct was inaugurated in 1907 and received its name in honour of Mr José Canalejas Méndez, Member of Parliament for the district of Alcoi.
The viaduct’s metal structure consists of 352 tonnes of steel, leaning on three piles and two supports. It has 162 metres long and in its origins its maximum height was 54 metres. At that time it was one of the most outstanding works of Spanish engineering.
