Boys’ toys don’t get much better than this. The two moveable sections of the bridge’s central span are called “bascules”, the French word for see-saw. Measuring 100ft long and weighing 1,000 tons, each pivots on a 2ft-thick steel rod and can be raised to a maximum angle of 87 degrees in just 90 seconds. Best of all – as I may have mentioned – I am about to be in charge of making this happen.
