Weedin Place fallout shelter

The Weedin Place Fallout Shelter is a disused fallout shelter in Seattle, Washington, United States. It was built in 1962–1963, under Interstate 5, to hold about 100 individuals. It had Diesel generators and other survival features and was intended to be the prototype "for countless similar shelters that would be installed nationwide under interstate highways".

The fallout shelter is categorized by Washington State Department of Transportation as a bridge, since it supports the southbound lanes of Interstate 5, and is eligible for inclusion in the National Register of Historic Places.

Prototype fallout shelter
As a prototype "community fallout shelter", the structure is considered "perhaps the only one of its kind in the world" and "apparently the first, and only, fallout shelter ever constructed in the U.S. under a public roadway".

The shelter is 3000 sqft with a circular main room 60 ft in diameter, and cost $57,000 to build. The walls are 15 inch thick concrete. It may have had an artesian well. It was engineered by Andersen-Bjornstad-Kane firm in Seattle.
