History

The IAT was proposed in 1994 by Richard Anderson, a Maine fisheries biologist, with plans to traverse the portions of the

in Maine, New Brunswick, and Quebec that the Appalachian Trail did not cover. Following route selection, construction of the trail took place through the late 1990s. The first person to thruhike the IAT, as it then existed, was John Brinda from Washington State, in 1997. He did this as part of a long-distance hike of what is known as the Eastern Continental Trail starting in Key West, Florida ending at Cap Gaspé in Quebec. He was the first person to thruhike the entire Eastern Continental Trail. The Newfoundland and Labrador extension to the IAT was proposed in 2003 and is still under construction. When completed, it will add an additional 1,200 km of trail. The official opening of the first trail section of the IAT Newfoundland was September 23, 2006. In 2009, IAT officials met with the
