The Trans Canada Trail, being promoted since 2016 as The Great Trail, is the world's longest network of recreational trails. It began construction in 1992. When fully connected, the Trail will stretch 24,000 kilometres (15,000 mi) from the Atlantic to the Pacific to the Arctic oceans. Just over 20,000 kilometres (12,000 mi) of the trail have been completed as of May 2016 and are usable, making the entire project approximately 86% complete. Two hundred forty gaps totalling 6,200 kilometres (3,900 mi) must be bridged in order to achieve a fully connected trail. The Trans Canada Trail has given itself until its 25th anniversary and Canada's 150th anniversary in 2017 to reach this objective.
