On June 15, 1907 an inspecting engineer noted that two girders of the anchor was 
misaligned by a quarter of an inch. Cooper called this a "not serious" problem. In 
the inspection report in August, 1907, it was noted that the girders had moved out 
alignment a bit more and "appeared bent". Although this condition was a bit more 
concerning, the work continued.

A period museum photo shows cranes atop the massive structure. The bridge

Tacoma Narrows Bridge collapsing, Tacoma, Washington, 1940 
On the morning of November 7, 1940, the Tacoma Narrows Bridge twisted violently in 42-mile-per-hour 
winds and collapsed into the cold waters of the Puget Sound. The disaster -- which luckily took 
no human lives -- shook the engineering community and forever changed the way bridges were 
built around the world. Roadway of Tacoma Narrows Bridge twisting violently in a windstorm,

Cable-supported bridges therefore play an important role in the overcoming of barriers that had split people, nations and even continents before. This cultural aspect is not less important.
