The Canal ran for 33 miles from the river Trent at West Bridgford, through 18 locks to Grantham. It was built primarily for the transportation of coal to Grantham. It opened in 1797 and its profitability steadily increased until 1841. It was then sold to to the Ambergate, Nottingham, Boston and Eastern Junction Railway (later bought by the Great Northern Railway), declined, and was finally closed in 1936. The location codes shown follow the CRT format and use their 'GR' prefix but theirs start near Grantham from where the canal is in water, just west of the A1, just over a mile from its original terminus in the town. In this archive it has been convention to list features along the canal in the same order as shown in Bradshaw's Canals and Navigable Rivers of England and Wales. Location codes therefore start at the River Trent.
