Construction of a [[Navigability|navigation]] from Salisbury to [[Christchurch, Dorset|Christchurch]] was authorised by the River Avon Navigation (Christchurch to New Sarum) Act 1664 ([[16 & 17 Cha. 2]]. c. 12). Work began in 1675 and the route was completed in 1684, but it fell out of use around 1715.<ref>{{HERR|mnumber=1031488|mname=Avon River Navigation|access-date=15 February 2022}}</ref> Canalised channels were dug to straighten sections of the river, including one through [[Britford]] parish just below Salisbury; a lock survives on this section near [[Longford Castle]], having been rebuilt in brick as a [[pound lock]] soon after the original [[flash lock]] was damaged by flooding in the early 18th century.<ref>{{HERR|mnumber=1011344|mname=Britford Lock|access-date=15 February 2022}}</ref>
