The Constitution Trail is a multi-use rail trail located in Illinois. It occupies an abandoned Illinois Central Gulf Railroad corridor that runs through the 'Twin Cities' of Bloomington and Normal in McLean County, Illinois.
The trail, which is owned by the municipalities of Bloomington and Normal, is used by bikers, inline skaters, walkers, runners and skiers, and covers approximately 24 mi. of former railways. It features the Camelback Bridge in Normal, a site on the U.S. National Register of Historic Places. Its official opening was May 6, 1989. In 2000, the trail was officially named a "Millennium Trail" by the White House Millennium Council.
