The Thames Tunnel – an old engraving c. 1850. The tunnel is built beneath the River Thames in London, connecting Rotherhithe and Wapping. It measures 35 feet (11 m) wide by 20 feet (6 m) high and is 1, 300 feet (396 m) long, running below the river. It was the first tunnel to have been constructed successfully underneath a navigable river. Using Marc Isambard Brunel's and Thomas Cochrane's newly invented tunnelling shield technology, it was built between 1825 and 1843 by Brunel and his son Isambard Kingdom Brunel. The tunnel was originally designed for horse-drawn carriages but proposals to extend the entrance to accommodate wheeled vehicles failed owing to cost, and it was used only by pedestrians ¬– this engraving showing a horse and cart is therefore somewhat misleading. It was later used by trains and now forms part of the London Overground railway network.
