The Longdon-on-Tern Aqueduct, near Longdon-on-Tern in Shropshire, was one of the first two canal aqueducts to be built from cast iron.
The cast iron canal aqueduct was re-engineered by Thomas Telford after the first construction designed by William Clowes was swept away by floods. It was built in 1796 to carry the Shrewsbury Canal across the River Tern near Longdon-on-Tern in Shropshire. [1] The 186 feet (57 m) aqueduct was opened one month after Benjamin Outram's 44 feet (13 m) cast iron Holmes Aqueduct on the Derby Canal, the world's first cast iron canal aqueduct. [1] [2] Since the closure of the Shrewsbury Canal in 1944, the aqueduct has been disused. [1] The aqueduct is an Historic England Grade I listed building and has been on the register since 30 March 1971. [2]
The canal was carried in a cast-iron trough 9 feet (2.7 m) wide, 3 feet (0.91 m) deep and 186 feet (57 m) long and divided in four spans, each of 47 feet 8 inches (14.53 m). [1]
Thomas Telford was a Scottish civil engineer. After establishing himself as an engineer of road and canal projects in Shropshire, he designed numerous infrastructure projects in his native Scotland, as well as harbours and tunnels. Such was his reputation as a prolific designer of highways and related bridges, he was dubbed the Colossus of Roads, and, reflecting his command of all types of civil engineering in the early 19th century, he was elected as the first president of the Institution of Civil Engineers, a post he held for 14 years until his death.
The Llangollen Canal is a navigable canal crossing the border between England and Wales. The waterway links Llangollen in Denbighshire, north Wales, with Hurleston in south Cheshire, via the town of Ellesmere, Shropshire. The name, which was coined in the 1980s, is a modern designation for parts of the historic Ellesmere Canal and the Llangollen navigable feeder, both of which became part of the Shropshire Union Canals in 1846.
The Pontcysyllte Aqueduct is a navigable aqueduct that carries the Llangollen Canal across the River Dee in the Vale of Llangollen in northeast Wales.
William Jessop was an English civil engineer, best known for his work on canals, harbours and early railways in the late 18th and early 19th centuries.
The Galton Bridge is a cast-iron bridge in Smethwick, near Birmingham, in the West Midlands of England. Opened in 1829 as a road bridge, the structure has been pedestrianised since the 1970s. It was built by Thomas Telford to carry a road across the new main line of the Birmingham Canal, which was built in a deep cutting. The bridge is 70 feet above the canal, making it reputedly the highest single-span arch bridge in the world when it was built, 26 feet wide, and 150 feet long. The iron components were fabricated at the nearby Horseley Ironworks and assembled atop the masonry abutments. The design includes decorative lamp-posts and X-shaped bracing in the spandrels.
Chirk Aqueduct is a 70-foot (21 m) high and 710-foot (220 m) long navigable aqueduct that carries what is now the Llangollen Canal across the Ceiriog Valley near Chirk, on the England-Wales border, spanning the two countries.
The River Tern is a river in Shropshire, England. It rises north-east of Market Drayton in the north of the county. The source of the Tern is considered to be the lake in the grounds of Maer Hall, Staffordshire. From here it flows for about 30 miles (48 km), being fed by the River Meese and the River Roden, until it joins the River Severn near Attingham Park, Atcham.
The Shrewsbury Canal was a canal in Shropshire, England. Authorised in 1793, the main line from Trench to Shrewsbury was fully open by 1797, but it remained isolated from the rest of the canal network until 1835, when the Birmingham and Liverpool Junction Canal built the Newport Branch from Norbury Junction to a new junction with the Shrewsbury Canal at Wappenshall. After ownership passed to a series of railway companies, the canal was officially abandoned in 1944; many sections have disappeared, though some bridges and other structures can still be found. There is an active campaign to preserve the remnants of the canal and to restore the Norbury to Shrewsbury line to navigation.
Longdon-Upon-Tern is a village in east central Shropshire, England. It is in the unitary district of Telford and Wrekin, and is approximately 11 kilometres (6.8 mi) east of Shrewsbury and 11 kilometres (6.8 mi) north-west of Telford. Longdon-Upon-Tern is situated on the River Tern, a tributary of the River Severn.
Navigable aqueducts are bridge structures that carry navigable waterway canals over other rivers, valleys, railways or roads. They are primarily distinguished by their size, carrying a larger cross-section of water than most water-supply aqueducts. Roman aqueducts were used to transport water and were created in Ancient Rome. The 662-metre (2,172 ft) long steel Briare aqueduct carrying the Canal latéral à la Loire over the River Loire was built in 1896. It was ranked as the longest navigable aqueduct in the world for more than a century, until the Magdeburg Water Bridge in Germany took the title in the early 21st century.
Cosgrove aqueduct is a navigable cast iron trough navigable aqueduct that carries the Grand Union Canal over the River Great Ouse, on the borders between Buckinghamshire and Northamptonshire at the northwest margin of Milton Keynes in England. The present structure was built in 1811, to replace a previous brick structure that had failed. When the present structure was erected, it was known as the "Iron Trunk". The structure has two cast iron trough spans, with a single central masonry pier. The abutments were constructed in masonry but have been refaced in brick during the twentieth century. The trough is 15 feet (4.6 m) wide, 6 ft 6 in (1.98 m) deep, with a total length of 101 feet (31 m). The canal surface is about 40 feet (12 m) above the surface of the river. There are large approach earthworks about 36 feet (11 m) high above the valley floor and 150 feet (46 m) wide, with a total length of half a mile (800m).
Mythe Bridge carries the A438 road across the River Severn at Tewkesbury. It is a cast-iron arch bridge spanning 170 feet (52 m) and 24 feet (7.3 m) wide, designed by Thomas Telford and completed in April 1826. It is a Grade II* listed structure.
Berwick Tunnel is a canal tunnel located on the Shrewsbury Canal, Shropshire, England, UK.
William Hazledine was an English ironmaster. Establishing large foundries, he was a pioneer in casting structural ironwork, most notably for canal aqueducts and early suspension bridges. Many of these projects were collaborations with Thomas Telford, including the Pontcysyllte Aqueduct and the Menai Suspension Bridge.
Stretton Aqueduct is a short cast iron canal aqueduct between Stretton and Brewood, and near to Belvide Reservoir, in south Staffordshire, England. Designed by Thomas Telford and bearing his name plus its date of construction, 1832, it carries the Shropshire Union Canal 30 feet (9.1 m) over the A5 road at a skewed angle.
William Reynolds was an ironmaster and a partner in the ironworks in Coalbrookdale in Shropshire, England. He was interested in advances in science and industry, and invented the inclined plane for canals.
Nantwich Aqueduct is a navigable aqueduct in Acton in Cheshire, England, which carries the Shropshire Union Canal over the Chester to Nantwich road. Designed by Thomas Telford, it dates from around 1826 and is listed at grade II*.
Ketley Ironworks was an ironworks in Ketley, in Shropshire, England. Established in 1756, it was one of the largest ironworks in Britain during its ownership by William Reynolds and his brother Joseph.
