The longest bike trail in the US stretches for a whopping 2,768 miles, beginning in Antelope Wells, New Mexico and ends in the snowy resort town of Banff in Alberta, Canada. But soon, a 2,900-mile, bike path called the Greenway will overtake it as the longest bike path in the US — and it won't share the road with cars.The Greenway will start in Key West, Florida and ends in Calais, Maine, right next to Canada. The project will essentially fill in the gaps between a chain of already existent bike paths — the route currently incorporates over 100 trails across 15 states, linking 25 cities.The East Coast Greenway Alliance started working on the path in 1992, and the group told the Atlantic's Citylab that the Greenway already incorporates some 850 miles of trails. By 2020, the organization plans to add 200 more, and the Alliance tells design magazine Core77 that it's planning to have 95% of the trail done by 2030.To read full story, click here.
