Port à l'Anglais Bridge

After plans for a cantilever bridge fell through, the local government finally commissioned a competition in 1912, accepting submissions for any design type.

Gisclard developed an innovative suspension system that involved the addition of suspender cables to a bridge's diagonal stays.

Adapting Gisclard's suspension system, however, the bridge's engineers improved on two qualities of structural art, efficiency and economy.

This design achievement comes at the expense of the structure's elegance in regard to the readability of load forces acting on the bridge.

Whereas Roebling’s design elegantly expresses this flow, the logic of the Gisclard-influenced cables is not as visually accessible.
