List of Washington state bridge failures

Washington is a state with many bodies of water to cross, including Puget Sound, Hood Canal, the Columbia River and numerous smaller rivers and creeks. It has experienced a number of bridge failures before and after the well known Tacoma Narrows Bridge collapse in 1940.

Causes

The single greatest cause of failure in Washington has been flooding, frequently associated with severe storms, which then results in destructive bridge scour.^[1][2][3] According to University of Washington meteorologist Cliff Mass, Western Washington is "particularly vulnerable to such bridge losses, with long floating bridges and the powerful winds associated with our terrain and incoming Pacific cyclones."^[3]

Causes of failure, 1923–1998^[a]

Cause	Number of failures
Flood	42
Fire	8
Volcanic mud and debris	5
Collision	4

Notes

1. Failures from Holstine and Hobbs analysis of 1923–1998 WSDOT data; excludes demolition, removal, replacement^[1]
2. Bridge failure data from WSDOT 1905–2009 list^[4] unless noted.
3. Deck rebuilt over existing steel arch^[11]
4. Some sources say a total of 27 bridges had to be replaced^[12][13][14]
5. Holstine and Hobbs say 7 bridges lost, this apparently does not count losses on minor tributaries of the Methow.^[18]
6. Rebuilt over existing steel structure^[11]
7. Floods in 1894 carried part of an upstream railroad bridge into the Division Street bridge in 1894; metal fatigue, shoddy steel, and a design flaw were also cited by contemporary sources^[23]
