A484 Footbridge using TensarTech Greenslope System
Tensar’s TensarTech GreenSlope system was used on the A484 footbridge to provide support to a curved approach ramp and the load bearing abutment. Given that this was a footbridge, aesthetics were an important factor so that it blended in with the local environment. Tensar’s solution also met the clients desire for giving users a positive experience when viewing and using the bridge.
Benefits
- Long design life
- Supported the carrying of the heavy bankseat loading
- Modular in design
- Small storage and construction footprint
GD Harries and Sons Ltd needed to build a 30.4m span bridge with a design life of 120 years, that was also visually appealing as well as to provide the best possible experience for pedestrians and cyclists. This included a complex spiral curved approach ramp, with a 1.4m high safety parapet and handrail on top to protect users. The client also required a system where the materials could be stored in a small compound next to a busy trunk road.
Tensar’s TensarTech GreenSlope system easily accommodated the curved geometry and provided a natural looking embankment. It was also capable of carrying the heavy bank seat loading and being modular in construction, made materials easy to store and enabled detailing of the required radius for the southern approach ramp simple
