Carter Harrison Crib Tunnel Collapse
In 1998 the tunnels leading from the Carter Harrison Crib to shore were de-watered for inspection, a process that was surrounded by controversy. Some experts feared that pumping the tunnels dry would result in a catastrophic collapse, while others guaranteed that collapse was not possible. Unfortunately, however, portions of the tunnel did in fact collapse. City lawyers soon filed suit against the engineers and contractors. The suit charged that the engineers, Alvord, Burdick & Howson, were negligent for advising the city that it was safe to drain the tunnels. It also charged that Luedtke Engineering Co., of Michigan, did the work in a way that caused the collapse. As a result of the collapse, the city spent $5.3 million to fill in a portion of the tunnel under Lake Shore Drive to prevent a possible additional collapse.
