Roads, bridges, canals and transportation, any way to move product and increase trade. Madison did not agree on this point he felt that the roads should be dealt with at a state level and vetoed the idea. It is here the transportation sub revolution begins.
To really understand the industrial revolution it is essential one grasps the importance of the transportation sub revolution. In the 1800 there is essentially no roads trough out the nation. All trade was done with a covered wagon. If it wasn't for Madison's veto we would have had a road system at this point. So a change in government mentality is essential. New England was opposed to using tax dollars for roads for it already had a good network for trade. The farmers and merchants needed the roads to survive. Madison just flat out thought it unconstitutional so he wouldn't budge and congress wasn't motivated to act in the interest of farmers and merchants. Private ventures took matter in their own hands and trails became roads. The river routes were developed. Trade was already going down river on barges and the barges then scrapped. This got the goods out of the interior of the nation for international sea export but didn't help get finished products back into an area of demand at prices most could afford. Rivers flow one way until Robert Fulton's steam boat. Now at a reasonable cost goods can be delivered in a timely manner up river 90% cheaper. New canals were dug to tie into the network of rivers the Erie Canal made New York the center of trade we know it as today effectively connecting Albany to Buffalo. Railroads are another innovation that makes this industry come to life. The first railroads were built in England by the 1920's the first lines were operating in the U.S. the train became a symbol of the era and was referred to as riding the lightning. The rail road connected the north east with the North West. The northern economy booms as an effect leaving the south behind to never catch up economically with the industry of the north.
