Wheaton Aston Aqueduct

Wheaton Aston Aqueduct
Shropshire Union

Just below Wheaton Aston's solitary lock and just before the BW service block, the Whiston Brook makes its way under the Shropshire Union Canal via a substantial brick archway. This is a pretty normal aqueduct structure for the Shropshire Union.

If you didn't know it was there you would never even notice it.

Ryehill Aqueduct

Ryehill Aqueduct
Shropshire Union

Aqueduct hunting sometimes throws up surprises, and this is one of them. The Ryehill Aqueduct (if that is what is is called) is a mystery structure, which is overlooked by both Pearson and GeoMaps - which is very strange given the latter's attention to detail.

Sure, the both recognise the passage of Marston Brook further south under the Wheaton Aston Embankment, but neither feature this most illuminating structure.

The Ryehill Aqueduct carries a disused access track under the northerly end on the Wheaton Aston Embankment via ha high vaulted archway. The really interesting feature it that within the tunnel the profile of the canal bed is visible in inch thick cast iron. I had always attributed the shallow sloping margins of the Shropshire Union to recent leak control measures, but this cast iron section suggests that the saucer shaped profile is original, and was therefore part of Telford's design.

And the overhead channel isn't the only mystery the aqueduct presents. Pinned high along its sides are chunky electrical cables, now disconnected and sagging down. Why have such a substantial power supply in the middle of nowhere? The answer probably lies in the brick structures in the adjacent fields, the remains of a world war two airfield. I assume that the tunnel and aqueduct served to connect two parts of the aerodrome, which was also the likely target of the bombers which hit a narrowboat in Wheaton Aston lock carrying unsheeted aluminium at night.

The question is: Which came first, the aqueduct or the airfield?

Who says that local history is boring!

Damside Aqueduct

Damside Aqueduct
Manchester Bolton and Bury Canal

The Damside Aqueduct is the missing structure on the Manchester Bolton and Bury Canal, demolished in 1965 for a road and river crossing at Darcy Lever.




I can only find this arial shot of the aqueduct, which will have to be rebuilt if the full canal restoration is ever to take place.

Norbury Aqueduct

Norbury Aqueduct
Shropshire Union

I knew that there was an aqueduct at Norbury cos the good book told me so.... but for the life of me I couldnt see it!

I wandered round the junction, peering down the embankment behind the BW office but nothing, not a stream, a road not even a footpath. I was on the point of giving up wen I saw a display board near the entrance to the marina, tracing out a local walk and there it was, about half a mile off to the south.



Norbury Aqueduct west

Well, I had tied up and was in no hurry so I wandered off down the lanes and finally came across it, and a very fine structure it is too, with impressive portals and a high barrel vaulted roof. As it pierces the foot of a very high embankment the tunnel is surprisingly long and so narrow that you wouldn't want to try walking through at the same time as an oncoming tractor.

Rather than retrace my steps I decided to scale the embankment and return via the towpath - easier said than done. The embankment is on the very edge of what is climbable without crampons, and even then it was only by using all fours from time to time, plus bits of ivy, low hanging branches and sundry weeds.

However, its a good aqueduct and well worth the effort.

River Penk Aquecuct at Pendeford

River Penk Aqueduct at Pendeford
Shropshire Union

The Penk is a significant river, one of four the Staffs and Worcester canal follows along its east west route. You would therefore expect the Shropshire Union's crossing to be a significant event, but in reality the river is so near it's source at Wergs that the resulting aqueduct is exceedingly humble.



River Penk Aqueduct at Pendeford

The watercourse passes through two very modest box culverts immediately to the south of Wolverhampton Boat Club at Pendeford, and were it not for the detail available on the Shropshire Union GeoMap you could very easily overlook it's presence altogether.
