The tunnel flooded again the following year, on 12 January 1828, by which six men died. Isambard was extremely lucky to survive this; the six men had made their way to the main stairwell, as the emergency exit was known to be locked. Isambard instead made for the locked exit. A contractor named Beamish heard him there and broke the door down, and an unconscious Isambard was pulled out and revived. He was sent to Brislington, near Bristol, to recuperate; there he heard about the competition to build what became the Clifton Suspension Bridge.
