Oak Ridge (WVLT) -- The Oak Ridge advisory board is hearing from the public on what should be done with the decrepit but historic K-25 building.
The Oak Ridge site specific advisory board is holding a forum at the Y-12 New Hope Center.
The mile-long u-shaped building was once the largest single building in the world.
Built during World War II, K-25 was apart of the Manhattan Project that enriched uranium for nuclear weapons.
The plan being considered by officials will preserve the north tower that is connected to two long wings and demolish the rest.
