The Assut de l'Or Bridge (Valencian: Pont de l'Assut de l'Or, Spanish: Puente de l'Assut de l'Or) is a dazzling white single-pylon cable-stayed bridge, designed by Valencian architect and civil engineer Santiago Calatrava, and completed in December 2008. The name l'Assut de l'Or means the Dam of the Gold and refers to a dam that was formerly located nearby - although locally it is referred to as "El Jamonero" (The Ham Holder)! The bridge is called the Serreria Bridge by its designer, Santiago Calatrava.^[1]

L'Agora and L'Assut de l'Or Bridge, with its 29 parallel cables stays, are two parts of Valencia's City of Arts and Sciences complex

Back stays of pylon to concrete counterweights in roadway

The bridge^[2] (crossing the Turìa Gardens) is located in central Valencia, Spain in its City of Arts and Sciences^[3] complex, which also includes a science museum (Museo de las Ciencias Principe Felipe^[4]), a covered plaza for concerts and sporting events (L'Àgora^[5]), the 3rd largest aquarium in the world (L'Oceanogràfic^[6]), a multifunctional arts complex and opera house (Palau de les Arts Reina Sofia^[7]) and, planetarium and Imax (L'Hemisfèric^[8])

The design of the bridge is a variant of Santiago Calatrava's pioneering 1992 design of a cantilever spar cable-stayed bridge in Seville, Spain. In the Serreria bridge, the pylon is curved backward (angle of the pylon was determined by an analysis of the counter forces against the cable stays) and also back-stayed to concrete counterweights in the roadway. The aesthetic effect of the Serreria bridge arises in part from the curved pylon and the 29 parallel cables supporting the bridge deck, accented at night by spot lighting of the cables and the pylon. The bridge deck has two carriageways, three lanes each for cars and one additional lane for a tramway, and another for pedestrian and cycle traffic, this last along the middle spine of the deck by the cable stays. Although the parallel cables and curved pylon are essentially in one vertical plane (see photos of the cables), because of the changing curvature of the pylon, like that of a planar spiral curve form, there might be an optical illusion when the bridge is view from the side (e.g., see side view photo above) that the pylon and the cables may appear to be not planar.
