Wallbridge Lower Lock Update No. 2

Wallbridge Update

Construction of Wallbridge Lower Lock Channel continues apace. The post & mesh revetment and coir matting along the north (non-towpath) side of the channel is now complete.

The task in hand

Abergavenny based ‘Alun Griffiths Construction’ team’s first task is to create a revetted navigable channel between Stroud Brewery Bridge and the derelict Wallbridge Lower Lock. The team will then install a dual purpose culvert… a) to carry excess water past the lock into the basin & channel below and b) to permit fish and eels migrating upstream.

‘Revetment’ defined

The dictionary definition of ‘revetment’ is “a retaining wall or facing of masonry or other material, supporting or protecting a rampart, wall, etc”. In this case the ‘other material’ is oolitic limestone. Construction team leader Kevin Sunderland was quick to point out the local connections… “The stone is delivered to site by the Gloucestershire firm Cullimores. The stone doesn’t have to come very far either….it is crushed oolitic limestone from Daglingworth Quarry near Cirencester”

Working westward

The navigation channel is being restored by working westward, from the gabions installed at the time of the construction of Stroud Brewery Bridge, towards the lock chamber. When the channel is complete the lock chamber will be restored by Cheltenham based Britannia Construction.

Navigable width revealed

The first picture shows the north side revetment now fitted with the timber fender along the top edge. The beginnings of the south side (towpath) side revetment can be seen in the foreground. The completed work now reveals the five metre width of the navigation channel.

The second of Mike Gallagher’s pictures shows the narrowness of the work site as a large dump truck is filled with material from the old channel on this tight bend in the canal.

A view from history

The final image is the famous painting of Stroud exhibited in Stroud's Museum in the Park.

The painting portrays the route of the Thames & Severn Canal through Stroud and demonstrates how the channel through Wallbridge has long been restricted by a tight bend. 

The painting dates from around 1790, at a time when wool was spun and woven into cloth in the small cottages where people lived. These were the days before large machinery was housed in huge mills such as Ebley.

The Thames & Severn Canal opened in 1789 and was a continuation of the Stroudwater Navigation which was completed in 1779 and terminated at Wallbridge Basin.

The unknown artist would have been sitting in fields along what is now Cainscross Road, somewhere close to Homebase.
