特倫特河
Some of the canals opening in the 1790s offered routes for traffic by-passing large sections of the River Trent. By 1796 the Derby Canal connected directly to the Erewash Canal at Sandiacre and the River Trent at Swarkestone. The Nottingham Canal ran from the Erewash Canal junction at Langley Mill, which itself linked to the Cromford Canal, down to the River Trent near Trent Bridge in Nottingham. Coal from Derbyshire could be transported to Nottingham and Derby without using the river.
