'Lottery bid success will make Stroud and Stonehouse canal towns after 70-year break'
'Stroud and Stonehouse are set to become canal towns once again, following The National Lottery Heritage Fund’s decision to grant £8.9 million to the Cotswold Canals Connected Project' - read more...
Also known as 'Cotswold Canals Connected' (CCC), the planned Phase 1b restoration section of the Stroudwater Navigation covers a distance of about 6.1 km (3.8 miles). This is between Saul Junction, with its connection to the national waterways network, and Ocean Railway Bridge in Stonehouse (see Phase 1b route).
Despite the relatively short distance, there are some significant challenges to overcome. These include obstructions due to the M5 motorway, the A38 (road) and a main-line railway.
The main elements of this restoration phase will include:
- reinstatement of about 1,600m (the 'missing mile') of infilled canal between the A38 and Oldbury Brook (Chipmans Platt, Eastington)
- establishment of a new Public Right of Way (towpath) along new canal section above (deferred from Phase 1a)
- new route under M5 (using existing river bridge)
- construction of new A38 road bridges (work in progress)
- moving utilities (pipes & fibre optic cables etc.)
- construction of a new railway bridge at Stonehouse
- reinstatement of three other bridges
- construction of two new locks
- restoration and/or refurbishment of a further 6 locks
- re-routing of an oil pipeline
- solutions for where the River Frome and Oldbury Brook cross the canal line
In April 2018 Stroud District Council were awarded Round One Development Funding (about £0.8M) from the National Heritage Lottery Fund (NHLF). This was in response to an application submitted to the NHLF in November 2017 for about £8.9M towards the cost of Phase 1b, estimated at £23M.
In addition to the NHLF funding, financial support will come from:
- Stroud District Council (SDC) £2.3m (more...)
- Gloucestershire County Council £700,000 (more...)
- Canal & River Trust (CRT) £625,000 plus additional support (more...)
- Highways England £4m towards restoration of 'missing mile' (more...)
The Cotswold Canals Trust will also contribute cash and volunteer resources.
A successful final-round grant application was submitted to the NHLF in May 2020 which resulted in a funding award for £8.9M being annouced in October 2020.
Phase 1b Restoration in more detail
This section gives an overview of the work required (some of which is already in progress) to fully restore the canal between Saul Junction and Stonehouse, which would then link Stroud to the national waterways network.
The route has been split into three sections heading from west to east:
- Saul Junction to the A38 (Road)
- A38 to Oldbury Brook (near Eastington)
- Oldbury Brook to Ocean Railway Bridge (Stonehouse)
In addition to the detail given below, other works would be required including upgrading or re-instating the towpath, dredging existing sections of canal, re-routing utilities and other engineering works.
Saul Junction to A38 (Road)
Walk Bridge: This low-level road bridge is the first major obstruction when travelling east from Saul Junction and would be replaced with a high-level fixed bridge.
Whitminster Bridge: Adjacent to Whitminster Lock this was once a farm access swing bridge, which is no longer operational. A Public Right of Way (EWH/21/3) crosses the canal here. This will likely be replaced with a manually-operated lift bridge similar in design to Lodgemore Bridge in Stroud, except it will have two overhead balance arms, not one.
Stonepitts Bridge: This former farm access hump-backed bridge has long-since been demolished. A Public Right of Way (EWH/21/3) crosses the canal here. This is likely to be replaced with same bridge design as Whitminster, described above.
Occupation Bridge: This carries a farm track over the canal and appears to be in good condition.
Partly restored by the Cotswold Canals Trust in the 1990s, but not gated. This lock would require some additional modifications for flood risk alleviation. Under the proposed scheme the lock will be entered from the River Frome when travelling from Stroud to Saul Junction.
Canal and River Frome
East of Whitminster Lock for a distance of about 660m the canal line, which used to run parallel to the River Frome, has been lost. Near the point where the canal reappears there used to be Lockham Aqueduct which carried the Frome under the bed of the canal.
The restored canal is likely to share the river course along this stretch, which was in fact the case when the canal was first built. (The canal was later separated to avoid constantly silting-up.)
An oil pipeline crosses the canal near Occupation Bridge and is an obstruction to navigation. This would need to be re-routed under the canal bed.
A38 to Oldbury Brook ('Missing Mile')
This section is often referred to as the 'missing mile' and was infilled when the M5 was built. The yellow items on the map below indicate where significant new structures would be built, including a new canal channel under an existing M5 underpass used by the River Frome.
A38 (Bristol Road) Bridges
The original route of the canal now bisects the A38/A419 roundabout in the top left corner of the above map.
The canal will pass across the A38 roundabout, and therefore, two separate bridges are required - which are curently under construction (2020).
New Canal Channel
The original canal route between the A38 and Westfield Bridge/Lock was infilled when the M5 motorway was built, and is represented by the broken brown line on the above map. Also shown is the site of Hyde's Bridge - long since demolished.
A new channel would be cut along the approximate route indicated by the black line on the map. The route shown is indicative only, and subject to landowner negotiations & agreement.
Replacement Bristol Road (BR) Lock
A new lock would be constructed to replace the original, which was lost during road improvements associated with the construction of the M5 motorway. The replacement lock would have less of a fall due to the insertion of another new lock east of the M5 to lower the level of the canal under the motorway.
M5 River Frome Underpass & New Canal Channel
To prevent the huge expense and disruption of constructing a purpose-built canal bridge across the M5, the preferred solution is to use the existing River Frome underpass.
A new concrete canal channel would be added alongside the river. As will be seen from the illustration below, the level of the canal would be lower than the normal river level, to achieve the required headroom.
A consequence of this solution is that during significant flood events the canal channel would be unusable.
New 'M5' Lock - Eastington
A new lock would be required east of the M5 near Westfield Lock to lower the level of the canal to provide sufficient headroom through the River Frome M5 underpass.
Westfield Bridge and Lock
Westfield Bridge is in fair condition and carries a Public Right of Way (EEA/37/2) over the canal.
The lock, which has been infilled, suffered significant structural damage caused when the Oldbury Brook channel was constructed (see below) and will need to be repaired / partly re-built.
The Oldbury Brook originally flowed into the canal at Meadow Mill and flowed out again using the Meadow Mill spill weir.
After canal abandonment, a new deep channel for Oldbury Brook was cut through the canal line at the tail of Westfield Lock, and the canal is now infilled either side.
A new aqueduct will be constructed here to take the watercourse under the canal..
Oldbury Brook to Ocean Railway Bridge
The four locks in this section (Dock, Pike, Blunder & Newtown) are in fair or good condition. Newtown and Blunder are operational, but Blunder Lock would probably require new top gates.
Dock and Pike Locks have been partly restored previously, but have not been operational since canal abandonment. Both require further repairs, paddle gear and gates.
There are three road bridges in this section; Pike, Roving and Bond's Mill.
Pike Bridge was rebuilt in 2005 and it is assumed that this is maintained by Gloucestershire Highways.
Roving Bridge appears to be well maintained and carries a track over the canal.
Bond's Mill Bridge, once a swing bridge, was replaced in 1994 with an all-composite (plastic) hydraulically-operated lift bridge.
Bond's Mill bridge is no longer operational, and the proposal here is to replace it with a lift bridge similar to the one at Lodgemore. The refurbished bridge would be electrically operated.
Ocean Railway Bridge
The most significant item in this section is a new railway bridge at Stonehouse. This would be constructed by Network Rail and would have to be scheduled into their long-term engineering plan, which could be as soon as spring 2021.
