Locks on the Kennet and Avon Canal

From Wikipedia, the free encyclopedia

There are a total of 105 locks on the Kennet and Avon Canal along its 87 miles (140 km) length from Bristol to the River Thames, including 6 on the navigable section of the River Avon from Bristol to Bath and 9 on the navigable section of the River Kennet to its confluence with the Thames near Reading. The remaining 90 locks lie along the 57 miles (92 km) of canal.

The Kennet and Avon Canal was built between 1794 and 1810 by John Rennie, to convey commercial barges carrying a variety of cargoes. It later fell into disuse and disrepair before being restored from 1970 to 1990. It is now fully navigable, mostly for leisure boating.

The following list numbers the locks from the River Avon in Bristol to the River Thames. It includes one lock that has been removed (98, Ufton Lock) and two that have been combined to form a single deep lock (8 and 9, now Bath Deep Lock). If travelling from Bristol to Reading, locks 1 to 54 are all uphill, and locks 55 to 107 are all downhill.
