Several waysides populate the secret cities of Los Alamos and Oak Ridge.



In Oak Ridge, interpretive waysides throughout the city share the story of the Manhattan Project in East Tennessee. At Los Alamos, interpretive waysides along the Kwage Mesa Trail describe life during the Manhattan Project on the isolated Pajarito Plateau. Wayside descriptions for both units are accessible below.
