Kennet and Avon Canal – Lock 87 - Ham Lock - Newbury, UK - Waterway Locks, Planes and Lifts on Waymarking.com

This is lock number 87 on the Kennet and Avon canal, known as Ham lock.

Like all locks on the Kennet and Avon between Bath and Reading the lock is a broad beam lock allowing craft with a maximum beam of 13’ 5” and 70-72’ in length. The locks between Bath and Hanham lock towards Bristol are broader, allowing craft up to 16’ beam with a maximum length of 75’. From Hanham lock down to Bristol harbour, craft with 18’ beam and 80’ long can be accepted. Then from Bristol harbour out to Avonmouth a beam of 50’ and a length of 325’ can be accommodated.

The canal is nearly 101 miles long with 104 locks and it was completed in three stages. The River Kennet was made navigable from Reading to Newbury and opened in 1723. The River Avon was made navigable from Bath to Bristol and opened in 1727. The final section was to build a canal between Newbury and Bath and this was opened in 1810. There is only one tunnel on the canal and that is a short one called Bruce’s tunnel at Savernake.

The canalisation of the River Kennet between Newbury and Reading was incredibly ambitious for the early 1700s as there is an overall elevation of 138’ requiring 20 locks in nearly as many miles.

At Devizes, the Caen Hill flight of 29 locks can be found, with 16 of them in a straight flight. It is a very popular tourist destination to see this amazing feat of engineering.

Trade ceased on the canal in 1930 but pleasure craft tried to keep it open and the last end to end run was made in 1951. The canal was restored during the 1980s and officially opened by HM The Queen on 8 August 1990.

Many of the aqueducts, especially at the western end, are splendid pieces of engineering and look pretty built out of local sandstone.
