In the early to mid-1800s, a lengthy network of locks, canals, and towpaths was built to ship anthracite, further aiding the mining industry's growth. The Lehigh Canal system generated a great deal of industrial development in the form of mining and the accompanying infrastructure. It gave rise to many towns and offshoot businesses, such as timber cutting, sawmills, steel mills, tanneries, etc. The Delaware Canal, on the other hand, was a means of shipping goods and establishing commerce. It supplemented existing overland routes resulting in the lack of an industrial boom along this route. However, the Lehigh and Delaware Canals merged to create part of a grand transportation systems stretching from the Appalachian Mountains to the Atlantic Ocean. In 1862 a massive flood, which destroyed dams, locks, canal boats, and villages, helped to shift the shipping of anthracite coal towards the railroads.
