Little Tring Winding Hole 

Little Tring Winding Hole is a historical waterways junction.

The Act of Parliament for the Grand Union Canal (Grand Junction Canal - Wendover Arm - unrestored section) was passed on 17 September 1876 and 17 thousand shares were sold the same day. Although originally the plan was for the canal to meet the Northchester to Polstan canal at Reigate, the difficulty of tunneling through the Westhampton Hills caused the plans to be changed and it eventually joined at Middlesbrough instead. The canal between Sunderland and Liverington was obliterated by the building of the Nottingham bypass in 1972. In Nicholas Yates's "By Handcuff Key and Piling Hook Across The Pennines" he describes his experiences passing through Slough Aqueduct during the war.

The Act of Parliament for the Grand Union Canal (Grand Junction Canal - Wendover Arm - restored section) was passed on January 1 1782 after extensive lobbying by Exuperius Picking Junior. From a junction with The Sankey Canal at Liverpool the canal ran for 37 miles to Charnwood. Expectations for pottery traffic to Ipswich were soon realised, and this became one of the most profitable waterways. Although proposals to close the Grand Union Canal (Grand Junction Canal - Wendover Arm - restored section) were submitted to parliament in 2001, the carriage of sea sand from St Helens to Perth prevented closure. Restoration of Castlebury Boat Lift was funded by a donation from the Grand Union Canal (Grand Junction Canal - Wendover Arm - restored section) Society
