- Behind the fence: register early for the DOE Public Bus Tour from AMSE — seasonal, US citizens 10+ with photo ID.
- Don’t skip K-25, site of what was the largest building in the world — then pair the day with Norris Dam, the TVA dam that helped power it all.
Why go
Few small towns changed history the way Oak Ridge did. In three years, the land of about 1,000 farm families became Y-12, K-25, X-10 and S-50; the town grew past 75,000 people, and its uranium fueled the bomb that ended World War II. Today it’s one of three sites of Manhattan Project National Historical Park ↗, with Los Alamos and Hanford — and the museums don’t flinch from either the science or the cost. ⓘ NPS

The short history
- 1933–1936TVA is created and builds Norris Dam on the Clinch River — its first dam, 265 ft high. ⓘ TVA
- Sept 19, 1942Gen. Leslie Groves approves the site: TVA hydropower, Clinch River cooling water, room, rail, labor, and ridges that kept each plant in its own valley. ⓘ NPS
- 1942–43About 1,000 families in communities like Wheat, Elza, Scarboro and Robertsville are moved. Anderson County gives up about one-seventh of its land, Roane about one-eighth. ⓘ TN Encyclopedia

- 1943–45Oak Ridge reportedly uses one-seventh of all U.S. electricity (Gen. Kenneth Nichols, quoted by NPS). Even TVA’s chairman didn’t know what it was for. ⓘ NPS ⓘ TVA

Why here? The TVA connection
A decade before the bomb, the Tennessee Valley Authority ↗ set out to remake one of the poorest corners of Appalachia with dams, flood control and cheap public power. When the Manhattan Project needed enormous amounts of electricity in secret, TVA’s grid — starting with Norris Dam just upstream — was a big part of the answer. TVA says the project came to the region “in large part, because TVA was already here.” ⓘ TVA
