This aqueduct, constructed by John Rennie Snr, is considered to be the finest in the North west.
NB - Please see the comment below. This rather beautiful photo of the Lune aqueduct is from NRT whose Flickr pages are something to behold. His (or her) photography is simply beautiful.
The aqueduct, with its five classical stone arches, carries the Lancaster Canal over the River Lune using a rusticated form of masonry. The piers were built in a hurry using special form of concrete incorporating Italian pozzolana powder, which allowed them to be finished before the 1794 /5 winter floods arrived.
The structure was, as ever, over budget at £48,000 - an overrun which played a large part in the plans to connect the canal to Preston being abandoned.

The thing about collecting aqueducts is the way that, one attuned to the word, they seem to crop up all over the place. I indulged myself by buying a copy of Waterways World (September 09) last weekend and was fascinated by Michael Coward's article on the above canal.
This ill fated waterway was as hopelessly over optimistic in its aspirations as it was underfunded. What was supposed to be a 45 mile waterway between Bradford on Avon to Poole on the south coast, with an 11 mile branch from Frome actually became an isolated 8 mile length, built around 1800, suspended in 1803 and given up for dead in 1825.
This waterway was therefore a spectacular failure, but it did leave some interesting remains in the form of two aqueducts :
The Coleford Aqueduct, a double arched effort which continues to stands tall and proud above Lover Coleford High Street.

An outing on the boat wouldn’t be complete without adding at least one new aqueduct to the collection. The southern end of the Shropshire union strikes off across the top end of the River Penk catchment basin, crossing numerous small tributaries, which trickle under the embankments via an assortment of tunnels and culverts. It’s this sort of terrain that causes trouble for ardent aqueduct hunters. Which of these passageways does one class as an aqueduct and which are mere culverts and therefore to be disregarded? My rule of thumb is that of the passageway is too small to be theoretically shuffled or canoed through, it isn’t a real aqueduct.
Not that an external investigation was easy. First there were the stinging nettles and then a very slippery bank with my descent only slowed by desperate grabs at the overhanging trees. Getting back up wasn’t a whole lot better! The archway is therefore included as proof of my perseverance, even if it could be argued that “it is only a culvert”.
South Brewood Aqueduct, tributory of the Penk
Not content with the northerly aqueduct we also took a walk past the more southerly stream, an unnamed but more substantial watercourse. This stream is accommodated by a substantial brick arch, similar in proportions to a typical canal bridge and probably created around the same former. The growth of seasonal vegetation prevented a descent photograph, with its outline more apparent to the naked eye. I will try and get a better shot of this structure during the winter months.

Stockport Branch Canal (disused arm of Aston Canal)
The Gorton aqueduct was originally constructed in stone in 1797 but was later replaced in 1906 with a steel structure spanning a newly widened railway, and remains in situ today. The second aqueduct also crossed a railway and was located mid way along the arm, a structure which has been demolished.
The line of the canal remains remarkably intact and whilst meaningful trade ceased in the 1930's, it was dredged in the 1950's before finally being abandoned in 1962, and infilled over the following decade. Given it's lack of scenic beauty it is remarkable that an active restoration society is hard at work seeking to reinstate this waterway. Maybe the gentrification of the Ashton Canal has reached a point where this side arm would be an attractive option, providing a safe mooring can be found at the far end.
