Could the inclusion of Canada in the early US have brought earlier federal support to infrastructure projects or bring success to projects that largely failed IOTL. George Washington had high hopes for the Potomac and was overseeing the construction on a canal up it till he became president that struggled with cost because of going around Great Falls and also struggled with manpower issues. New York issued charters to companies, one to connect the lakes and to improve navigation on the Mohawk river and another to connect the Hudson to Lakes George and Champlain which failed to do anything because of lack of money. The early congress was hesitant to fund road projects for a lot of different reasons and Alexander Hamilton had proposed investing in infrastructure and manufactures from the federal government but unlike his report on credit didn't include an actual plan. What else might have come? An earlier Welland Canal, Trent Severn, National Road, or any other number of canals or roads with an actual national plan to it.
