The idea of a tunnel under the Thames was first suggested in 1798 and a tunnel was begun in 1805 under the direction of Richard Trevithick. An exceptionally high tide in January 1808 innundated the workings just 200 feet from completion and it was abandoned. Marc Isambard Brunel took up the challenge to dig a tunnel fifteen years later at a site some way downstream of the original using a revolutionary tunnelling shield inspired by ship worms, In April 1826 the twenty year old Isambard Kingdom Brunel was put in charge of the project and in spite of two floods, one of which nearly cost him his life, the tunnel was completed in March 1843. It is still used though is now part of the London Underground East London Line.

In the 1830's Isambard undertook a commission to drain the marshes at Tollesbury in Essex.

In 1830 Brunel won the competition for a bridge over the Avon gorge at Clifton though due to local civil unrest the construction was delayed for five years only to be abandonned again due to lack of funds. The bridge was eventually completed in 1864, after Brunel's death,

Paddington Station. In March 1833 Brunel was appointed engineer to the Great Western Railway. Plans were completed by March 1834. It then took another two years to go through Parliament. The first section from Paddington to Maidenhead was opened on 4 June1838.

Brunel also designed three great ships, each the largest of its age, the Great Western, the Great Britain and the Great Eastern. The second of these was begun in 1839 and launched in 1843 finally entering service in 1846. It had a chequered career ending as a floating warehouse in the Falkland Islands where she was finally beached in 1937. In 1970 she was brought back to Bristol where she is being restored.

The GWR at Dawlish. Originally the western extension of the GWR between Exeter and Newton Abbot was powered by a revolutionary atmospheric system. Fixed steam engines created a vacuum in a cast iron pipe between the tracks which sucked the trains along, it worked quite well for a time but limited technical capabilities of the time and rats eating the leather seals led to the abandonment of the system.

One of Brunel's most dramatic technical achievements is the Royal Albert Bridge over the River Tamar at Saltash in Cornwall. Begun in 1854, the two 465 foot cast iron spans were hoisted into position in September 1856 and July 1858 and the bridge was opened by the Prince Consort in May 1859.
