A former nuclear weapons complex along the South Carolina-Georgia border is opening its doors to the public.
The Savannah River Site says a pilot tour program in April was so successful that it will offer another round of public tours, starting in September.
Organizers say the four-hour tours will feature stops at the Savannah River Ecology Laboratory, as well as drives by two towns relocated when the site was founded in the early 1950s.
Participants must be U.S. citizens who are at least 18 years old and have valid photo identification.
Thousands worked at SRS during the Cold War, churning out materials for the nation's nuclear weapons cache. Now, much of the work at the site is focused on cleaning up those materials.
