The Bridges

Three bridges each representing a different century - although two will have been opened by the same reigning monarch.
The third Forth Bridge at Queensferry, the Queensferry Crossing, which is the longest bridge, is being opened by the Queen next week. It will then close to traffic for two days to allow the lucky people whose name came out of the ballot to walk across it. Unlike the second bridge, this one doesn't have a cycle or pedestrian lane so it will not normally be possible to walk across it.
Lucky people, sadly, none of my friends in Edinburgh were lucky in the ballot.
