Inside the Thames Tunnel in the mid-19th century. The Thames Tunnel is a tunnel beneath the River Thames in London, connecting Rotherhithe and Wapping.It measures 35 ft (11 m) wide by 20 ft (6.1 m) high and is 1,300 ft (400 m) long, running at a depth of 75 ft (23 m) below the river surface measured at high tide.
The Thames Tideway Tunnel, due for completion in 2025, will be a 25 km (16 mi) long tunnel running mostly under the tidal section of the River Thames through central London to capture, store and convey almost all the raw sewage and rainwater that currently overflows into the river.
The world's first underwater tunnel was the Thames Tunnel by Marc Brunel built in 1843, designed for horse-drawn carriages but used as a pedestrian route; since 1869 the tunnel has carried trains on the East London Line. The Tower Subway (1870) was briefly used for a railway; later came all the deep-level tube lines.
Tunnels under the River Thames, from east to west are: Thames Cable Tunnel, between Tilbury and Gravesend, commissioned in 1970, comprising two 400 kV circuits between Tilbury and Kingsnorth substations [28] Dartford Cable Tunnel, between Littlebrook substation and West Thurrock substation, constructed 2003–04, comprising two 400 kV circuits [29]
In 1805 the Thames Archway Company was formed with the intention of driving a tunnel beneath the Thames between Rotherhithe and Limehouse. Richard Trevithick was engaged by the company to construct the tunnel. He used Cornish miners to work on the tunnel. In 1807 the tunnel encountered quicksand and conditions became difficult and dangerous.
The Thames Commissioners were also in financial difficulties, and the Thames was almost unnavigable from Oxford to Lechlade after 1855. In 1866, plans to convert the canal to a railway were rejected by Parliament, but the Thames Commissioners were replaced by the Thames Conservancy, and most of the river was soon returned to a navigable state.

A major part of London's water supply infrastructure, the initial ring was constructed by Thames Water between 1988 and 1993 at a cost of £248 million (equivalent to £638 million in 2023), and when completed, it was the longest tunnel in the UK.
