William Jessop inherited from his father a natural ability in engineering, and because of his father's association with John Smeaton in the construction of Eddystone Lighthouse he was accepted by Smeaton as a pupil in 1759 at the age of 14. Smeaton was so impressed with his ability that Jessop was retained as an assistant after completion of his pupilage in 1767. As such he carried out field-work, making surveys on his own, but in 1772 he was recommended to the Aire and Calder Committee as an independent engineer and his first personally prepared report was made on the Haddlesey Cut, Selby Canal. It was in this report that he gave his first evidence before a Parliamentary Committee. He later became Resident Engineer on the Selby Canal, and soon after he was elected to the Smeatonian Society of Engineers, of which he later became Secretary for twenty years. Meanwhile he accompanied Smeaton to Ireland to advise on the Grand Canal, ultimately becoming Consulting Engineer until 1802, and was responsible for Ringsend Docks, which connected the canal to the Liffey and were opened in 1796. From 1783 to 1787 he advised on improvements to the River Trent, and his ability was so recognized that it made his reputation. From then on he was consulted on the Cromford Canal (1789–93), the Leicester Navigation (1791–4) and the Grantham Canal (1793–7); at the same time he was Chief Engineer of the Grand Junction Canal from 1793 to 1797 and then Consulting Engineer until 1805. He also engineered the Barnsley and Rochdale Canals. In fact, there were few canals during this period on which he was not consulted. It has now been established that Jessop carried the responsibility for the Pont-Cysyllte Aqueduct in Wales and also prepared the estimates for the Caledonian Canal in 1804. In 1792 he became a partner in the Butterley ironworks and thus became interested in railways. He proposed the Surrey Iron Railway in 1799 and prepared for the estimates; the line was built and opened in 1805. He was also the Engineer for the 10 mile (16 km) long Kilmarnock \& Troon Railway, the Act for which was obtained in 1808 and was the first Act for a public railway in Scotland. Jessop's advice was sought on drainage works between 1785 and 1802 in the lowlands of the Isle of Axholme, Holderness, the Norfolk Marshlands, and the Axe and Brue area of the Somerset Levels. He was also consulted on harbour and dock improvements. These included Hull (1793), Portsmouth (1796), Folkestone (1806) and Sunderland (1807), but his greatest dock works were the West India Docks in London and the Floating Harbour at Bristol. He was Consulting Engineer to the City of London Corporation from 1796to 1799, drawing up plans for docks on the Isle of Dogs in 1796; in February 1800 he was appointed Engineer, and three years later, in September 1803, he was appointed Engineer to the Bristol Floating Harbour. Jessop was regarded as the leading civil engineer in the country from 1785 until 1806. He died following a stroke in 1814.

Telford was the son of a shepherd, who died when the boy was in his first year. Brought up by his mother, Janet Jackson, he attended the parish school at Westerkirk. He was apprenticed to a stonemason in Lochmaben and to another in Langholm. In 1780 he walked from Eskdale to Edinburgh and in 1872 rode to London on a horse that he was to deliver there. He worked for Sir William Chambers as a mason on Somerset House, then on the Eskdale house of Sir James Johnstone. In 1783–4 he worked on the new Commissioner's House and other buildings at Portsmouth dockyard.

In late 1786 Telford was appointed County Surveyor for Shropshire and moved to Shrewsbury Castle, with work initially on the new infirmary and County Gaol. He designed the church of St Mary Magdalene, Bridgnorth, and also the church at Madley. Telford built his first bridge in 1790–2 at Montford; between 1790 and 1796 he built forty-five road bridges in Shropshire, including Buildwas Bridge. In September 1793 he was appointed general agent, engineer and architect to the Ellesmere Canal, which was to connect the Mersey and Dee rivers with the Severn at Shrewsbury; William Jessop was Principal Engineer. This work included the Pont Cysyllte aqueduct, a 1,000 ft (305 m) long cast-iron trough 127 ft (39 m) above ground level, which entailed an on-site ironworks and took ten years to complete; the aqueduct is still in use today. In 1800 Telford put forward a plan for a new London Bridge with a single cast-iron arch with a span of 600 ft (183 m) but this was not built.

In 1801 Telford was appointed engineer to the British Fisheries Society "to report on Highland Communications" in Scotland where, over the following eighteen years, 920 miles (1,480 km) of new roads were built, 280 miles (450 km) of the old military roads were realigned and rebuilt, over 1,000 bridges were constructed and much harbour work done, all under Telford's direction. A further 180 miles (290 km) of new roads were also constructed in the Lowlands of Scotland. From 1804 to 1822 he was also engaged on the construction of the Caledonian Canal: 119 miles (191 km) in all, 58 miles (93 km) being sea loch, 38 miles (61 km) being Lochs Lochy, Oich and Ness, 23 miles (37 km) having to be cut.

In 1808 he was invited by King Gustav IV Adolf of Sweden to assist Count Baltzar von Platen in the survey and construction of a canal between the North Sea and the Baltic. Telford surveyed the 114 mile (183 km) route in six weeks; 53 miles (85 km) of new canal were to be cut. Soon after the plans for the canal were completed, the King of Sweden created him a Knight of the Order of Vasa, an honour that he would have liked to have declined. At one time some 60,000 soldiers and seamen were engaged on the work, Telford supplying supervisors, machinery—including an 8 hp steam dredger from the Donkin works and machinery for two small paddle boats—and ironwork for some of the locks. Under his direction an ironworks was set up at Motala, the foundation of an important Swedish industrial concern which is still flourishing today. The Gotha Canal was opened in September 1832.

In 1811 Telford was asked to make recommendations for the improvement of the Shrewsbury to Holyhead section of the London-Holyhead road, and in 1815 he was asked to survey the whole route from London for a Parliamentary Committee. Construction of his new road took fifteen years, apart from the bridges at Conway and over the Menai Straits, both suspension bridges by Telford and opened in 1826. The Menai bridge had a span of 579 ft (176 m), the roadway being 153 ft (47 m) above the water level.

In 1817 Telford was appointed Engineer to the Exchequer Loan Commission, a body set up to make capital loans for deserving projects in the hard times that followed after the peace of Waterloo. In 1820 he became the first President of the Engineers Institute, which gained its Royal Charter in 1828 to become the Institution of Civil Engineers. He was appointed Engineer to the St Katharine's Dock Company during its construction from 1825 to 1828, and was consulted on several early railway projects including the Liverpool and Manchester as well as a number of canal works in the Midlands including the new Harecastle tunnel, 3,000 ft (914 m) long.

Telford led a largely itinerant life, living in hotels and lodgings, acquiring his own house for the first time in 1821, 24 Abingdon Street, Westminster, which was partly used as a school for young civil engineers. He died there in 1834, after suffering in his later years from the isolation of deafness. He was buried in Westminster Abbey.
