Richmond Lock is a halftide lock and barrage that also incorporates a public footbridge. The barrage is formed of three vertical sluice gates suspended from the footbridge superstructure. Apart from periods about two hours either side of high tide, the sluice gates are closed and boats have to use the conventional lock on the right side of the photo. Around high tide the sluice gates are raised into the footbridge superstructure and boats can pass through unimpeded. The lock is the most downstream on the River Thames and is the only one to be operated by the Port of London Authority.
