The Limehouse Cut is a straight, broad canal in the East End of London, England, which linked the lower reaches of the Lee Navigation to The River Thames. It now connects to Limehouse Basin as a result of changes made in 1968. The Cut turns in a broad curve from Bow Locks, where the Lee Navigation meets Bow Creek; it then proceeds directly south-west for 2 miles (3.2 km) through the London Borough of Tower Hamlets to Limehouse Basin.
Factories and warehouses line the Cut for the initial section of the cut above Limehouse Basin, but whereas they used to be serviced by the canal they are now serviced by roads. Most use of the canals is for pleasure, both on the water and beside the water on the towpaths. Regent's Canal, the Hertford Union Canal, the Lee Navigation and the Limehouse Cut form a four-sided loop, covering a distance of 5.5 miles (8.9 km), which can be walked or cycled. The scenic towpaths cut across roads and railways in the area, providing a distinct viewpoint.
Access on foot along the Limehouse Cut was difficult in the area below the Blackwall Tunnel approach road, but was made easier as a result of an innovative scheme to create a floating towpath. This was opened in July 2003 and consisted of 60 floating pontoons, creating a 240-metre (262 yd) walkway complete with green glowing edges.
The Cut is part of the Lee Navigation and is administered by British Waterways. It was built for sailing barges, and can accommodate vessels which are 88 by 19 feet (27 by 5.8 m). Headroom is limited to 6.75 feet (2.06 m). The lock from Limehouse Basin to the Thames was originally a ship lock, but has been replaced with a smaller one. Although the area around Limehouse Basin and the original lock into the Thames have been extensively developed as part of the Docklands Regeneration scheme, the row of houses overlooking the lock, which were built in 1883 by the Lee Conservators, have been retained and refurbished, while the site of the lock is now a shallow pool. At the end of the London 2012 torch relay, David Beckham arrived with the Olympic torch on a speedboat via the Limehouse Cut to the Olympic opening ceremony.
