What makes Tower Bridge so unique is its bascule mechanism! โ
๏ธ This means that part of the bridge can lift up to let big ships pass through. Each bascule weighs about
1,000 tons! When a ship needs to go through, a signal is given, and the bridge begins to raise. It takes about 5 minutes for the bascules to lift completely! The bridge can be raised up to 86 degrees! ๐ข
Isnโt that amazing? This clever engineering helps keep the river open for all kinds of vessels.
