The Forth and Clyde Canal crosses Scotland, providing a route for sea-going vessels between the Firth of Forth and the Firth of Clyde at the narrowest part of the Scottish Lowlands. The canal is 35 miles (56 km) long and its eastern end is connected to the River Forth by a short stretch of the River Carron near Grangemouth.
Designed by John Smeaton, construction started in 1768 and, after delays due to funding problems, the canal was completed in 1790.
