Looking north from Bosley Locks No 2, east of North Rode. On the Macclesfield Canal there are twelve locks in the flight at Bosley, allowing a rise in water level of 118 feet (36 metres). The Macclesfield Canal is just over 27 miles in length, and has thirteen locks, including the stop lock at Hall Green and the other twelve at Bosley. The canal was surveyed by Thomas Telford in 1825, then engineered by William Crosley, and opened on 9 November 1831 at a cost of £320,000. It links the Trent and Mersey Canal at Hall Green to the Peak Forest Canal at Marple.
