A huge milestone has been reached as the Hanford site crosses the 75th anniversary finish line and Visit Tri-Cities has unveiled a new website to promote the three-site Manhattan Project National Historical Park.

According to a Post on Visit Tri-Cities.com:

Once completed, the Manhattan Project National Historical Park, will tell the story of historic and scientific sites at Hanford, as well as Manhattan Project-related sites at Los Alamos, New Mexico, and Oak Ridge, Tennessee. The funding and approval of the park was established by Congress late in 2014. It will be the first National Historical Park of its kind, combining multiple locations as one Manhattan Project National Park.
