| Nickey.com posted Narrow boats crossing the Llangollen Canal on Pontcysyllte Aqueduct, North East Wales. See More: nickeyscircle.com/pontcysyllte-aqueduct-in-wales/ Nickey.com posted Express Way Explorers posted Glynis Waghorn: “Drove” a canal boat across here on a very windy day and walkers had to keep pushing the boat away from the walkway as the wind was blowing the boat against the side. Scary, memorable and fun 🤩 For the love of Narrowboats posted Stunning view of the Pontcysyllte Aqueduct Finished in 1805 after a 10 year design and build program and is the longest aqueduct in the UK. Designed by Thomas Telford and William Jessop....although many just accredit it to the former. The original plan was to create a series of locks down both sides of the valley to an embankment that would carry the Ellesmere Canal over the River Dee....that would have been one hell of a set of locks.. After Telford was hired the plan was changed to an aqueduct that would create an uninterrupted waterway straight across the valley. Despite considerable public skepticism, Telford was confident his construction method would work because he had previously built a cast-iron trough aqueduct – the Longdon-on-Tern Aqueduct on the Shrewsbury Canal. Granted World Heritage status in 2009 |
"Its nineteen cast-iron spans carry the waterway 126 feet / 38.4 metres above the river, and for two centuries it remained the tallest navigable aqueduct in the world....It is the first great masterpiece of civil engineer Thomas Telford (1757–1834) and formed the basis of his outstanding international reputation." [cadw]
"The aqueduct is 1,007ft (307m) long....Telford's design for the aqueduct saw workers build 18 slender stone piers [columns] 125ft (38m) high. To save weight and material the piers were hollow from about 70ft (21m). The canal itself was carried in a trough made of cast iron plates. The trough was 12ft (3.7m) wide and 5.5ft(1.7m) deep."

| abcboathire [The arches were constructed with four cast-iron segments.] |
When my wife and I visited England, I was surprised by how much the old canal system was still used for recreation.

| bbc, arpingstone historic-uk also has this photo [This is another source that put the opening date at 1805 instead of 1795. Was the aqueduct done in 1795, but it couldn't be effectively used until 1805 when the canal was finished?] |

| Duck & Cover, Growing Up in the Atomic Age posted Pontcysyllte Aqueduct, Great Britain, one of the greatest feats of engineering, spans the Dee Valley and has been in use for over 200 years. The aqueduct is a UNESCO World Heritage Site. Sally Vernon: The Wynn's went over it and did a video https://www.youtube.com/watch?v=J8Z3D0IH2Os |
