I’ve featured the Millennium Bridge a few times: once with bollards, once during the removal of the bollards, and once without them. But today is the first time I’ve featured it tilted!

It cost £22m to build, and tilted for the first time in 2001. It’s so energy efficient that it costs just £3.60 in electricity to open. One thing that many people don’t realise is that the tilting of the bridge has a secondary function, beyond letting ships pass: it tips any litter dropped on the bridge into special traps, making the bridge uniquely self-tidying!
