Caledonian Canal
The Caledonian Canal connects the Scottish east coast at Inverness with the west coast at Corpach near Fort William in Scotland. The canal was built in the early nineteenth century by the Scottish engineer Thomas Telford.  It is about 60 miles (100 kilometres) long and reaches 106 feet (32 metres) above sea level. Only one third of the entire length is man-made, the rest is made up of Loch Dochfour, Loch Ness, Loch Oich, and Loch Lochy  in the Great Glen. There are 29 locks,  four aqueducts and 10 bridges in the course of the canal.
