James P. Taylor of Burlington was the secretary of both the Vermont Division of the T.R.I. Highway Association and of the Greater Vermont Association. He wrote many promotional items, including the 1921 Vermont guide to the Roosevelt Highway.
Vermont's 1921 brochure included this map of the route across the state. Although not detailed enough to be used when motoring, it shows the general path of the trail across the state over what would become U.S. Route 2.
