The Limehouse Cut is a short canal in East London that connects the Lee Navigation to the Regent's Canal at Limehouse Basin. The canal begins (or ends depending on your point of view) at Bow Locks.
It then travels 2 miles through Tower Hamlets until it meets the Regent's Canal at Limehouse Basin which is where the canal joins the Thames. Originally the Limehouse Cut connected directly onto the Thames but that was changed in 1968 because of the need to replace the river lock. Instead a new short length of canal was built to connect the Limehouse Cut to Limehouse Basin allowing traffic to use the river lock there instead.
