Puente Colgante, Valladolid, Tied-arch bridge in Valladolid, Spain

The Puente Colgante is a bowstring bridge over the Pisuerga in Valladolid, linking the Avenida de Salamanca with the Paseo de Zorrilla. Its deck is carried by two large metal lattice arches, and the structure stands 31.6 metres above the riverbed. It was inaugurated on 20 April 1865, the first bridge of its type built in Spain.

The first bridge here was a suspension bridge begun in 1852 to a design by engineer Andrés Mendizábal, but work stopped in 1854 with only the abutments built. The present bowstring structure, promoted by José de Salamanca and backed by Queen Isabella II, opened on 20 April 1865 as Spain's first bridge of its type. It kept the old name and the earlier abutments.

Locals call it both Puente Colgante and Puente de Prado, a name inherited from the 1852 suspension bridge whose abutments were the only parts built before works stopped in 1854. The present bowstring structure kept that misleading name. The bridge carries the street of the same name, linking Avenida de Salamanca with Paseo de Zorrilla.

The bridge carries the street of the same name, linking Avenida de Salamanca with Paseo de Zorrilla, and its deck stands 31.6 m above the riverbed. The 1852 abutments, 19 m tall, still support the 1865 structure. The walkway is open to pedestrians crossing the Pisuerga.

The bridge employs a bowstring design where the horizontal deck absorbs forces from the arch. This allowed for a sleek appearance without the massive foundations that traditional arch bridges require.
