Macalloy Tension Bars used to help support stunning bridge.
Macalloy Tension Bars were used on the elegant double-arched bridge spanning the River Saône in Lyon, France. The award winning crossing, was put in place to ease congestion (for both cars and pedestrians), on the city’s existing bridges. The unusual twisted arches act as the primary structural element, creating a dramatic piece of sculpture with their unique, twisting, gull-wing form.
Macalloy engineers worked with the steel fabricators, to design a special M90 fork end to go with the M85 diameter bars, allowing for a spherical bearing. This was to in order to allow for additional misalignment, required for the design of the bridge.
The steel Tension Rods were tensioned using Macalloy’s Techno-Tensioner device – a device that enables on-site stressing of Tension Rods.
