Caledonian Canal is a canal which links east coast at Inverness with west coast at Corpach near Fort William, in Scotland. It was built in the nineteenth century by Scottish engineer Thomas Telford , and is related with Gotta Canal in Sweden, built by Telford, too. The canal flows about 97 km (60 miles) from northeast to southwest. Just a part of the whole length is made by humans and the other part is supplied by Loch Dochfour, Loch Ness, Loch Oich and Loch Lochy. The lakes mentioned are situated in the Great Glen, on a ageological fault in the Earth's shell . There are 4 aqueducts, 29 lakes and 10 bridges in the path of this canal.
