In the late 1800s major ore discoveries in the Coeur D'Alene mining district led to the development of a railroad line used to transport ore to the smelter. Heavy metals such as lead, cadmium, arsenic and zinc were released along the length of the railroad. As a part of a legal settlement, the Union Pacific Railroad Company partnered with the EPA, the Idaho Department of Environmental Quality, and the Coeur D’Alene tribe to undertake a Rails-to-Trails conversion of this Superfund site. Now, with the rails removed, the paved trail serves a dual purpose as a remedial cap and as a 73-mile bike path. The design also adapted historic structures for trail use. The trail was named winner of the 2006 EPA Region 10 Phoenix Award for achievement of excellence in brownfield redevelopment.
