Thomas Telford FRS, FRSE (9 August 1757 – 2 September 1834) was a Scottish civil engineer, architect and stonemason, and road, bridge and canal builder. 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 (a pun on the Colossus of Rhodes), 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.
Telford was born on 9 August 1757 at Glendinning, a hill farm 3 miles east of Eskdalemuir Kirk, in the rural parish of Westerkirk, in Eskdale, Dumfriesshire. His father John Telford, a shepherd, died soon after Thomas was born. Thomas was raised in poverty by his mother Janet Jackson (died 1794).
At the age of 14 he was apprenticed to a stonemason, and some of his earliest work can still be seen on the bridge across the River Esk in Langholm in the Scottish borders. He worked for a time in Edinburgh and in 1782 he moved to London where, after meeting architects Robert Adam and Sir William Chambers, he was involved in building additions to Somerset House there. Two years later he found work at Portsmouth dockyard and — although still largely self-taught — was extending his talents to the specification, design and management of building projects.
In 1787, through his wealthy patron William Pulteney, he became Surveyor of Public Works in Shropshire. Civil engineering was a discipline still in its infancy, so Telford was set on establishing himself as an architect. His projects included renovation of Shrewsbury Castle, the town's prison (during the planning of which he met leading prison reformer John Howard), the Church of St. Mary Magdalene, Bridgnorth and another church, St Michael, in Madeley. Called in to advise on a leaking roof at St Chad's Church Shrewsbury in 1788, he warned the church was in imminent danger of collapse; his reputation was made locally when it collapsed 3 days later, but he was not the architect for its replacement.
As the Shropshire county surveyor, Telford was also responsible for bridges. In 1790 he designed a bridge carrying the London–Holyhead road over the River Severn at Montford, the first of some 40 bridges he built in Shropshire, including major crossings of the Severn at Buildwas, and Bridgnorth. The bridge at Buildwas was Telford's first iron bridge. He was influenced by Abraham Darby's bridge at Ironbridge, and observed that it was grossly over-designed for its function, and many of the component parts were poorly cast. By contrast, his bridge was 30 ft (10 m) wider in span and half the weight, although it now no longer exists. He was one of the first engineers to test his materials thoroughly before construction. As his engineering prowess grew, Telford was to return to this material repeatedly.
In 1795, the bridge at Bewdley in Worcestershire was swept away in the winter floods and Telford was responsible for the design of its replacement. The same winter floods saw the bridge at Tenbury also swept away. This bridge across the River Teme was the joint responsibility of both Worcestershire and Shropshire and the bridge has a bend where the two counties meet. Telford was responsible for the repair to the northern (Shropshire) end of the bridge.
Telford's reputation in Shropshire led to his appointment in 1793 to manage the detailed design and construction of the Ellesmere Canal, linking the ironworks and collieries of Wrexham via the north-west Shropshire town of Ellesmere, with Chester, utilising the existing Chester Canal, and then the River Mersey.
Among other structures, this involved the spectacular Pontcysyllte Aqueduct over the River Dee in the Vale of Llangollen, where Telford used a new method of construction consisting of troughs made from cast iron plates and fixed in masonry. Extending for over 1,000 feet (300 m) with an altitude of 126 feet (38 m) above the valley floor, the Pontcysyllte Aqueduct consists of nineteen arches, each with a forty-five foot span. Being a pioneer in the use of cast-iron for large scaled structures, Telford had to invent new techniques, such as using boiling sugar and lead as a sealant on the iron connections. Eminent canal engineer William Jessop oversaw the project, but he left the detailed execution of the project in Telford's hands. The aqueduct was designated a UNESCO World Heritage Site in 2009.
The same period also saw Telford involved in the design and construction of the Shrewsbury Canal. When the original engineer, Josiah Clowes, died in 1795, Telford succeeded him. One of Telford's achievements on this project was the design of Longdon-on-Tern Aqueduct, the cast-iron aqueduct at Longdon-on-Tern, pre-dating that at Pontcysyllte, and substantially bigger than the UK's first cast-iron aqueduct, built by Benjamin Outram on the Derby Canal just months earlier. The aqueduct is no longer in use, but is preserved as a distinctive piece of canal engineering.
The Ellesmere Canal was completed in 1805 and alongside his canal responsibilities, Telford's reputation as a civil engineer meant he was constantly consulted on numerous other projects. These included water supply works for Liverpool, improvements to London's docklands and the rebuilding of London Bridge (c.1800).
Most notably (and again William Pulteney was influential), in 1801 Telford devised a master plan to improve communications in the Highlands of Scotland, a massive project that was to last some 20 years. It included the building of the Caledonian Canal along the Great Glen and redesign of sections of the Crinan Canal, some 920 miles (1,480 km) of new roads, over a thousand new bridges (including the Craigellachie Bridge), numerous harbour improvements (including works at Aberdeen, Dundee, Peterhead, Wick, Portmahomack and Banff), and 32 new churches.
Telford also undertook highway works in the Scottish Lowlands, including 184 miles (296 km) of new roads and numerous bridges, ranging from a 112 ft (34 m) span stone bridge across the Dee at Tongueland in Kirkcudbright (1805–06) to the 129 ft (39 m) tall Cartland Crags bridge near Lanark (1822).
Telford was consulted in 1806 by the King of Sweden about the construction of a canal between Gothenburg and Stockholm. His plans were adopted and construction of the Göta Canal began in 1810. Telford travelled to Sweden at that time to oversee some of the more important initial excavations.
Many of Telford's projects were undertaken due to his role as a member of the Exchequer Bill Loan Commission, an organ set up under the Poor Employment Act of 1817, to help finance public work projects that would generate employment.
During his later years, Telford was responsible for rebuilding sections of the London to Holyhead road, a task completed by his assistant of ten years, John MacNeill; today, much of the route is the A5 trunk road, although the Holyhead Road diverted off the A5 along what is now parts of A45, A41 and A464 through the cities of Coventry, Birmingham and Wolverhampton. Between London and Shrewsbury, most of the work amounted to improvements. Beyond Shrewsbury, and especially beyond Llangollen, the work often involved building a highway from scratch. Notable features of this section of the route include the Waterloo Bridge across the River Conwy at Betws-y-Coed, the ascent from there to Capel Curig and then the descent from the pass of Nant Ffrancon towards Bangor. Between Capel Curig and Bethesda, in the Ogwen Valley, Telford deviated from the original road, built by Romans during their occupation of this area.
On the island of Anglesey a new embankment across the Stanley Sands to Holyhead was constructed, but the crossing of the Menai Strait was the most formidable challenge, overcome by the Menai Suspension Bridge (1819–26). Spanning 580 feet (180 m), this was the longest suspension bridge of the time. Unlike modern suspension bridges, Telford used individually linked 9.5-foot (2.9 m) iron eye bars for the cables.
Telford also worked on the North Wales coast road between Chester and Bangor, including another major suspension bridge at Conwy, opened later the same year as its Menai counterpart.
Further afield Telford designed a road to cross the centre of the Isle of Arran. Named the 'String road', this route traverses bleak and difficult terrain to allow traffic to cross between east and west Arran avoiding the circuitous coastal route. His work on improving the Glasgow – Carlisle road, later to become the A74, has been described as "a model for future engineers."
Telford improved on methods for the building of macadam roads by improving the selection of stone based on thickness, taking into account traffic, alignment and slopes.
The punning nickname Colossus of Roads was given to Telford by his friend, the eventual Poet Laureate, Robert Southey. Telford's reputation as a man of letters may have preceded his fame as an engineer: he had published poetry between 1779 and 1784, and an account of a tour of Scotland with Southey. His will left bequests to Southey (who would later write Telford's biography), the poet Thomas Campbell (1777–1844) and to the publishers of the Edinburgh Encyclopædia (to which he had been a contributor).
In 1821, he was elected a foreign member of the Royal Swedish Academy of Sciences.
An Act of Parliament in 1823 provided a grant of £50,000 for the building of up to 40 churches and manses in communities without any church buildings (hence the alternative name: 'Parliamentary Church' or 'Parliamentary Kirk').The total cost was not to exceed £1500 on any site and Telford was commissioned to undertake the design. He developed a simple church of T-shaped plan and two manse designs – a single-storey and a two-storey, adaptable to site and ground conditions, and to brick or stone construction, at £750 each. Of the 43 churches originally planned, 32 were eventually built around the Scottish highlands and islands (the other 11 were achieved by redoing existing buildings). The last of these churches was built in 1830. Some have been restored and/or converted to private use.
Other works by Telford include the St Katharine Docks (1824–28) close to Tower Bridge in central London, where he worked with the architect Philip Hardwick, the Gloucester and Berkeley Ship Canal (today known as the Gloucester and Sharpness Canal), Over Bridge near Gloucester, the second Harecastle Tunnel on the Trent and Mersey Canal (1827), and the Birmingham and Liverpool Junction Canal (today part of the Shropshire Union Canal) – started in May 1826 but finished, after Telford's death, in January 1835. At the time of its construction in 1829, Galton Bridge was the longest single span in the world. He also built Whitstable harbour in Kent in 1832, in connection with the Canterbury and Whitstable Railway with an unusual system for flushing out mud using a tidal reservoir. He also completed the Grand Trunk after James Brindley died due to being over-worked.
In 1820, Telford was appointed the first President of the recently formed Institution of Civil Engineers, a post he held until his death.
He was Initiated into Freemasonry in Antiquity Lodge, No. 26, (Portsmouth, England) in 1770. This lodge no longer exists. He was a founder member of Phoenix Lodge, No. 257 (also in Portsmouth). Telford designed a room within the George Inn for the lodge.In 1786 he became an affiliate member of Salopian Lodge, No. 262 (Shrewsbury, England).
Telford's young draughtsman and clerk 1830–34 George Turnbull in his diary states:
On the 23rd [August 1834] Mr Telford was taken seriously ill of a bilious derangement to which he had been liable … he grew worse and worse … [surgeons] attended him twice a day, but it was to no avail for he died on the 2nd September, very peacefully at about 5pm. … His old servant James Handscombe and I were the only two in the house [24 Abingdon Street, London] when he died. He was never married. Mr Milne and Mr Rickman were, no doubt, Telford's most intimate friends. … I went to Mr Milne and under his direction … made all the arrangements about the house and correspondence. … Telford had no blood relations that we knew of. The funeral took place on the 10th September [in Westminster Abbey]. … Mr Telford was of the most genial disposition and a delightful companion, his laugh was the heartiest I ever heard; it was a pleasure to be in his society.
Thomas Telford was buried in the nave of Westminster Abbey; a statue was erected to him nearby, in St Andrew's Chapel adjoining the north transept.
Throughout his life Telford had a great affection for his birthplace of Eskdale and its people and in his will left legacies to the two local libraries at Westerkirk and Langholm.
In 2011 he was one of seven inaugural inductees to the Scottish Engineering Hall of Fame.
George Turnbull states that Telford wrote and gave him a poem:
(Turnbull includes notes that explain nine references to Burns's life in the poem.)
Turnbull also states:
His ability and perseverance may be understood from various literary compositions of after life, such as the articles he contributed to the Edinburgh Encyclopædia , such as Architecture, Bridge-building, and Canal-making. Singular to say the earliest distinction he acquired in life was as a poet. Even at 30 years of age he reprinted at Shrewsbury a poem called "Eskdale", … Some others of his poems are in my possession.
Telford designed a number of bridges and aqueducts during his career. They include:

When a new town was being built in the Wrekin area of Shropshire in 1968, it was named Telford in his honour. In 1990, when it came to naming one of Britain's first City Technology Colleges, to be situated in Telford, Thomas Telford was the obvious choice. Thomas Telford School is consistently among the top performing comprehensive schools in the country.

Telford Hall is a hall of residence at Loughborough University named after Thomas Telford. A plaque in his honour hangs in the hall's common room.
The Borough of County Line in Montgomery County, Pennsylvania changed its name to Telford in 1857, after the North Pennsylvania Railroad Company named its new station there "Telford" in honour of Thomas Telford.
Edinburgh's Telford College (incorporated into Edinburgh College since October 2012), was named in honour of the famous engineer.
In 2008, a footbridge was erected over the Shubenacadie Canal in Dartmouth, Nova Scotia and named for Telford who made important contributions to the nineteenth century Canadian canal.
Telford's autobiography, titled The Life of Thomas Telford, Civil Engineer, written by himself, was published in 1838.
The Ellesmere Canal was a waterway in England and Wales that was planned to carry boat traffic between the rivers Mersey and Severn. The proposal would create a link between the Port of Liverpool and the mineral industries in north east Wales and the manufacturing centres in the West Midlands. However, the canal was never completed as intended because of its rising costs and failure to generate the expected commercial traffic.
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 north east Wales. The 18-arched stone and cast iron structure is for use by narrowboats and was completed in 1805 having taken ten years to design and build. It is the longest aqueduct in Great Britain and the highest canal aqueduct in the world.
Horseshoe Falls is a weir on the River Dee near Llantysilio Hall in Denbighshire, Wales, about 5 kilometres (3 mi) north-west of the town of Llangollen.
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.
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 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. Although Roman aqueducts were sometimes used for transport, aqueducts were not generally used until the 17th century when the problems of summit level canals had been solved and modern canal systems were developed. 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.
Craigellachie Bridge is a cast iron arch bridge across the River Spey at Craigellachie, near to the village of Aberlour in Moray, Scotland. It was designed by the renowned civil engineer Thomas Telford and built from 1812 to 1814. It is a Category A listed structure.
The Almond Aqueduct, also known as the Lin's Mill Aqueduct, is a navigable aqueduct that carries the Union Canal over the River Almond in Scotland, west of Ratho, Edinburgh.
The Slateford Aqueduct is a navigable aqueduct that carries the Union Canal over the Water of Leith at Slateford, Edinburgh, Scotland. Completed in 1822, it has eight arches and spans a length of 500 feet (150 m).
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.
The Avon Aqueduct is a navigable aqueduct that carries the Union Canal over the River Avon, near Linlithgow, Scotland.
Hugh Baird was a Scottish civil engineer, who designed and built the Union Canal. Born at Westertown, Bothkennar, Stirlingshire, he was the son of Nicol Baird, surveyor to the Forth and Clyde Canal, and was a younger brother of engineer Charles Baird.
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*.
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.
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.
