Bridge
A bridge is a structure which enables people to cross something like water, a railway, road or a valley. A bridge will usually be designed by an engineer to be strong enough to let something cross and stable enough that it will stay in place for a long time.
Some bridges have special features, for example Tower Bridge in London has a road section which lifts to allow taller boats to pass through.
