 The over-all logo reads "Canada to Gulf" where the local name would be, and most MRPC publications denote the route as beginning in Ontario and ending in Louisiana.The Great River Road is not a single road but a designated route along connected segments of named and numbered highways and streets maintained by state, county, or local jurisdictions.Until the early 1980s, a single Canada-to-Gulf alignment of the Great River Road, serving all ten states, was eligible for special federal funding.
