The Machines That Built America’s Underground Cities — Before Modern TBMs

Explore the 1828 Thames Tunnel flood, a disaster that nearly ended the career of a young Isambard Kingdom Brunel. On January 12, 1828, a catastrophic flood struck the excavation site beneath the River Thames. This incident offers a grim look at the dangers inherent in 19th century engineering, where workers faced immense pressure and treacherous conditions long before modern safety standards existed. We examine the specific challenges of early tunnel construction and the methods used during this era. By looking at the images and records from this event, we gain perspective on the risks Brunel and his crew navigated during their ambitious industrial history project.
