Oakham Canal
United Kingdom
The Oakham Canal ran from Oakham, Rutland to Melton Mowbray, Leicestershire in the East Midlands of England. It opened in 1802, but it was never a financial success, and it suffered from the lack of an adequate water supply. It closed after 45 years, when it was bought by the Midland Railway to allow the Syston and Peterborough Railway to be built, partly along its course. Most of it is infilled, although much of its route can still be seen in the landscape, and there are short sections which still hold water.
