Infrastructure (Roads/Rivers/Canals)

The growth of the population and of the towns and cities is supported by infrastructure, some a natural part of the land and others supported by government or private investments. Among the former are the nation’s rivers which are traversed by canoes, barges, masted vessels, and eventually steam ships. Some flow north and south:

Others flow east and west, and play a crucial role in opening up the new states west of the Appalachian Mountain range. The longest eastern river, the Ohio, becomes the official line of demarcation in 1787 between the “free” states of the North and the “slave” states of the South.

To the north, across eastern Canada, the St. Lawrence River – Great Lakes system, runs 2,340 miles from the Atlantic coast to the tip of Lake Superior. This route will prove especially providential to the fur trade, which is already booming in 1820.

Roads also play an important part in linking population centers and moving the nation ever westward. Most begin as Tribal hunting trails that are converted over time into major thoroughfares and then in the 1820’s upgraded with crushed stone popularized by Scottish engineer, John McAdam.

Most early roads run north to south, with the longest being the 975 mile King’s Highway connecting Boston to Charleston.
