Many people answer "a drawbridge" to this..... but, technically a drawbridge is either 'raised' or 'lowered'. However, the famous Tower Bridge in London carries road traffic across the river Thames. But as the photos of it show, the bridge is split in the middle and each side can be raised at an angle to allow ships to pass up and down the river. So, when Tower Bridge is open to road traffic it is closed to shipping, and when it is closed to road traffic it is open to shippping.
It is called the drawbridge if it can be lifted and lowered.
