Construction of a super-slender footbridge is forging ahead in Turin, Italy. The $2M, 140m long river crossing has a complex, curved geometry made up of intersecting toroids, which means its width grows and shrinks from 5m to 8m, while its depth ranges from 1.2m to just 600mm.
The bridge is supported by two sculpted, reinforced concrete piers in the river. The deck is a steel box with internal stiffeners.
Designer UK firm Whitby Bird has set out to achieve the illusion of complex, threedimensional curves on the under side of the bridge by breaking the surface down into multiple facets.
Contractors is Italian firm Tecno 3. Completion is scheduled for March next year.
