William Jessop and the Pontcysyllte Aqueduct built by Thomas Telford. It is known as the Cosgrove aqueduct and was designed and built by Bevan. Two tunnels also had to be built, at Braunston and Blisworth. The Blisworth Tunnel caused great problems, and was unfinished when the rest of the canal was ready. In fact Jessop considered abandoning it and using locks to carry the canal over the ridge. Jessop's temporary solution was a railway line laid over the ridge to carry traffic until the tunnel was completed. The Grand Junction Canal was enormously important in encouraging trade between London and the Midlands.
