Fontana Lake formed when Fontana Dam flooded the Little Tennessee River. The dam was completed in 1945, submerging communities including Proctor, Judson and Fontana and displacing more than 1,000 people; wartime power from the dam also served Oak Ridge and the Manhattan Project. A 1943 agreement promised a road along the lake's north shore so displaced residents could reach cemeteries and community sites. Construction of the road, then called North Shore Road, began in the 1960s and stopped in 1972 because of unstable slopes, cost and environmental challenges. The tunnel at the end of Lakeview Drive is the unfinished remnant of that plan.
