WASHINGTON, D.C.—The U.S. House of Representatives has passed a bill that would create a Manhattan Project National Historical Park that would include Oak Ridge, federal officials said Thursday afternoon.

Passage of the bill, pursued for years by historic preservationists, was announced by U.S. Senator Lamar Alexander and Representative Chuck Fleischmann, both Tennessee Republicans. It was an amendment to the National Defense Authorization Act, or NDAA, which passed in a 300-119 vote.

The bill would designate three sites that were part of the World War II-era Manhattan Project. Besides Oak Ridge, the sites include Los Alamos, New Mexico, and Hanford, Washington. The U.S. Senate is expected to pass the 2015 NDAA legislation without amendments before adjourning for the Christmas recess, perhaps as early as next week, according to the Atomic Heritage Foundation, a Washington, D.C.-based nonprofit that has helped lead efforts to establish the park for more than a decade.

The Manhattan Project was a top-secret federal program to build the world’s first atomic bombs. Oak Ridge sites that would be included in the park are the Beta-3 racetracks and Alpha Calutron magnets at Y-12 National Security Complex and the K-25 Building site at the East Tennessee Technology Park.
