Editing Cable-stayed bridge (section)

===Cantilever spar cable-stayed bridge===
Far more radical in its structure, the [[Puente del Alamillo]] (1992) uses a single [[Cantilever spar cable-stayed bridge|cantilever spar]] on one side of the span, with cables on one side only to support the bridge deck. Unlike other cable-stayed types, this bridge exerts considerable overturning force upon its foundation and the spar must resist the bending caused by the cables, as the cable forces are not balanced by opposing cables. The spar of this particular bridge forms the [[gnomon]] of a large garden [[sundial]]. Related bridges by the architect [[Santiago Calatrava]] include the [[Puente de la Mujer]] (2001), [[Sundial Bridge]] (2004), [[Chords Bridge]] (2008), and [[Assut de l'Or Bridge]] (2008).
