Overview
The canal system grew rapidly at first, and became an almost completely connected network covering the South, Midlands, and parts of the North of England and Wales. There were canals in Scotland, but they were not connected to the English canals or, generally, to each other (the main exception being the Monkland Canal, the Union Canal and the Forth and Clyde Canal which connected the River Clyde and Glasgow to the River Forth and Edinburgh). As building techniques improved, older canals were improved by straightening, embankments, cuttings, tunnels, aqueducts, inclined planes, and boat lifts, which together snipped many miles and locks, and therefore, hours and cost, from journeys.
