The Gateshead Millennium Bridge, a normal bridge that people can walk across and does what normal bridges do, except that it can tilt. This bridge is kind of like a draw bridge and lets ships pass under it.
Here is a super cool time-lapse video to understand how this bridge tilts.
This bridge fits in with engineering because of how it tilts to let boats pass through and tilts back to let pedestrians pass. this is a very special bridge because it is not a wide spreed design because of how big it is and how hard it is to build.
