The truth about Unity 3
You will be aware that opponents of the Cable-Stay Footbridge believe that an alternative bridge could have a graceful arch and would have “potential savings of £400,000”. We now more and can see that this is not true.
This montage will shock some people. It shows the Unity 3 bridge for the first time from the sort of angle from which people will really see it – bulky, obtrusive and right at eye-height from just one building’s length away. It was produced by the engineering firm employed by the Preservation Trust.
We also now know that the claims of £400,000 savings are not true. The Preservation Trust’s latest costing is £110,000 more than before. This is just the first of the cost problems. The surface of Unity 3 (we will not walk on bare-metal) has been paired to the bone. The Town Council could save 4 tons in weight on the Cable-Stay Bridge and therefore tens of thousands of pounds by doing the same, but there would be a risk that the surface would more quickly wear through to bare metal.
The Preservation Trust’s engineers are also note the risk of wobble – like the Millennium Bridge in London. This could be prevented with “damping”, but is likely to add tens of thousands to the cost – much more if it was done afterwards!
There would also be tens of thousands of pounds in design costs alone to iron out all the issues that Unity 3 has landing on the banks at an angle and with a gradient. Even the supporters montage on this site shows Unity 3 cutting a swathe across the footpath.
All this simply demonstrates to me that the logic and simple elegance of the Cable-Stay Bridge are right. Please Back the Bridge.
