The Grand Junction Canal Company were concerned about these delays to the opening of the important route to the east Midlands, which would bring traffic onto their canal from the River Trent and the Nottinghamshire and Derbyshire coalfields. They requested James Barnes and Thomas Telford to revisit the question of route once again, and they developed a plan for a canal to link the part of the Leicestershire and Northamptonshire Union Canal which had been built with the Grand Junction Canal, which had been fully open since 1805.
