Cable-stayed bridges with more than three spans involve significantly more challenging designs than do 2-span or 3-span structures.

In a 2-span or 3-span cable-stayed bridge, the loads from the main spans are normally anchored back near the end [[abutment]]s by stays in the end spans. For more spans, this is not the case and the bridge structure is less stiff overall. This can create difficulties in both the design of the deck and the pylons.
Examples of multiple-span structures in which this is the case include [[Ting Kau Bridge]], where additional 'cross-bracing' stays are used to stabilise the pylons; [[Millau Viaduct]] and [[Mezcala Bridge]], where twin-legged towers are used; and [[General Rafael Urdaneta Bridge]], where very stiff multi-legged frame towers were adopted. A similar situation with a suspension bridge is found at both the [[Great Seto Bridge]] and [[San Francisco–Oakland Bay Bridge]] where additional anchorage piers are required after every set of three suspension spans – this solution can also be adapted for cable-stayed bridges.<ref>{{cite journal
