I am currently spending some time on the river Weaver before resuming my journey north to the Leeds and Liverpool Canal. The river Weaver is a navigation canal (parts of the river have been dug as a canal to improve navigation) that mainly served the salt production in the area.
Built in 1875 to raise and lower boats to the nearby Trent and Mersey Canal it closed in 1983 due to rust. After refurbishment it reopened in 2002.
The gears at the top are original, but no longer raise and lower the boats as it is done hydraulically these days.
