They were replaced by the Colin P Witter Lock built in the early 1970s next to the old site of the Lucy's Locks . The lock has steel girder supports due to the depth of the lock and the unstable nature of the ground. Much of the work was done by volunteers from Gloucester prison. The gates were donated by the Port of London Authority from the abandoned Grand Surrey Canal.
