The Concrete TT is a quick and easy build
The heavy duty 0.85 HN full concrete beam access bridge is pre-cast off site, and most bridges take just three to five days to install. This concrete design is especially suited to areas where coastal or geothermal corrosion can affect the lifespan of the bridge. Your bridge is ready in no time and built to drive on immediatly post build.
Double T Concrete Bridges are constructed from pre-stressed, pre-cast concrete beams with built-in continuous concrete kerbs on either side to contain and direct effluent when used on farms. The maximum axle loading is up to 7.5 tonne single axle and 15 tonne dual axle. The balustrades and pipe handrails are made from galvanised steel, the bridges are designed to Transit New Zealand Bridge Manual Standards.
