Bath Bottom Lock, which is numbered as No 7 on the canal, is the meeting with the River Avon just south of Pulteney Bridge.
A road constructed while the canal was in a state of disrepair passes over the original site of the lower lock.
[3] The new chamber has a depth of 5.92 metres (19 ft 5 in),[4] making it Britain's second deepest canal lock.
Cleveland tunnel is 52.7 metres (173 ft) long and runs under Cleveland House, the former headquarters of the Kennet and Avon Canal Company.
[12][13][14][15][16][17] The locks were restored in 1968 by a collaboration involving staff from British Waterways and volunteer labour organised by the Kennet and Avon Canal Trust.
