High Quality Content by WIKIPEDIA articles! The Manchester Ship Canal is a 36-mile (58 km) long river navigation in North West England. Designed to give the city of Manchester direct access to the sea, it was built between 1887 and 1894 at a cost of about Pds. 15 million ( Pds. 1.22 billion as of 2009), and in its day was the largest navigation canal in the world. The canal generally follows the original route of the rivers Mersey and Irwell, and along its course uses several sets of locks. The canal is able to accommodate a range of vessels, from coastal ships to inter-continental cargo liners, but it is not large enough for all modern vessels. A railway was built to transport goods to and from the docks located alongside the canal. The canal is no longer considered to be an important shipping route, but it still carries about six million tonnes of freight each year. It is now operated under private ownership.
