Avon and Clifton Suspension Bridge- Isambard Kingdom Brunel

Isambard Kingdom Brunel, FRS (/ˈɪzəmbɑrd brˈnɛl/; 9 April 1806 – 15 September 1859), was an English mechanical and civil engineer who is considered "one of the most ingenious and prolific figures in engineering history",[1] "one of the 19th century engineering giants",[2] and "one of the greatest figures of the Industrial Revolution, [who] changed the face of the English landscape with his groundbreaking designs and ingenious constructions".[
Brunel is perhaps best remembered for designs for the Clifton Suspension Bridge in Bristol. The bridge was built to designs based on Brunel's, but with significant changes. Spanning over 702 ft (214 m), and nominally 249 ft (76 m) above the River Avon, it had the longest span of any bridge in the world at the time of construction.[23] Brunel submitted four designs to a committee headed by Thomas Telford, but Telford rejected all entries, proposing his own design instead. Vociferous opposition from the public forced the organising committee to hold a new competition, which was won by Brunel.

Great Britain

Brunel had become convinced of the superiority of propeller-driven ships over paddle wheels. After tests conducted aboard the propeller-driven steam tug Archimedes, he incorporated a large six-bladed propeller into his design for the 322-foot (98 m) Great Britain, which was launched in 1843.[65] Great Britain is considered the first modern ship, being built of metal rather than wood, powered by an engine rather than wind or oars, and driven by propeller rather than paddle wheel. She was the first iron-hulled, propeller-driven ship to cross the Atlantic Ocean.[66] Her maiden voyage was made in August and September 1845, from Liverpool to New York. In 1846, she was run aground at Dundrum, County Down. She was salvaged and employed in the Australian service.[67] And today she is fully preserved and open to the public in Bristol, UK.
