North Idaho Centennial Trail is a twenty-four-mile paved route in northern Idaho that serves both transportation and recreation, running from Higgens Point on Lake Coeur d'Alene along the lake's north shore, through Coeur d'Alene and Post Falls, to the Idaho-Washington border, where it connects with Washington's Spokane River Centennial Trail as part of a longer regional corridor. The trail emerged from planning after Expo '74, with Washington beginning work for its centennial in 1989 and Idaho extending the route for its own centennial in 1990. Public art by David Clemons at the trail's ends links present-day use with people and activities from a century earlier.
