History of the Basingstoke Canal
The Basingstoke Canal is in the south east of England and flows through the counties of Hampshire and Surrey. It originally ran from the Hampshire town of Basingstoke to its junction with the River Wey Navigation in Surrey, 37 miles away.
Today, 32 miles of the original navigation have been restored, from the Wey Navigation as far as North Warnborough in Hampshire, as a public amenity catering for boaters, walkers, canoeists, anglers and naturalists.
It has 29 locks, all but one in Surrey, which together raise the canal 204ft from the River Wey. You can find more about the Basingstoke Canal here.
This cache is beside the Crookham swing bridge, also known as Zebon Copse Swing Bridge, which was rebuilt in 1954 after several collapses, and was reconstructed again in 1992-3 to bring it up to modern requirements. The swing bridge, which carries a bridleway, provides access from the towpath to Zebon Copse. It is 8ft wide and replaced an earlier footbridge of steel and timber. It is counter-balanced, which makes it fairly easy to move (if you have the key to the padlock). It pivots on a circular plate supported by twenty-four 3" diameter steel ball bearings and is one of only two swing bridges on the canal. (The other is at the Canal Centre in Mytchett, Surrey).
