The Grantham Canal was opened in 1797 and ran for a distance of 33 miles from the River Trent at Trent Bridge Nottingham to the centre of Grantham. The canal carried commercial traffic until 1929.
Between 1940/60s some of the original humped back bridges were removed and the canal culverted under the roads.
The link to the Trent has been severed by improvements to the West Bridgeford area of Nottingham, at the Grantham end is cut short by the A1 close ot Harlaxton, although the canal is in water on the other side of the A1 it is not used as a waterway, the canal towpath continues for some way towards the centre of Grantham.
Today the canal is used by walkers and cyclists, it forms a part of the long distance Viking Way footpath, and an improtant part of the Sustrans network of cycle paths.
