About the Seattle nuclear fallout shelter under I-5, the only one in the US

In November 1962, solely a month after the Cuban Missile Disaster, excavation of a shelter in Seattle started.

It was anticipated to be the primary of a number of fallout shelters throughout the U.S., however ended up being the one one constructed within the nation.

The Could 15, 1962, Seattle Occasions recognized the construction as “the nation’s first fallout shelter to be constructed right into a freeway.”

Designed by the Seattle engineering agency Anderson Bjornstad Kane and constructed by McDonald Building of Seattle for $67,300, the shelter is situated underneath southbound Interstate 5, on the north finish of the Ravenna Bridge.

As soon as development of the shelter started, contractors got solely 120 days to construct it.

The shelter was devoted on March 29, 1963.

“It’s a reasonably minimal shelter, and it’s not really a bomb shelter, it’s a fallout shelter,” Scott Williams of the Washington State Division of Transportation advised KIRO-FM Radio in 2018. “So, it wasn’t designed to outlive a direct nuclear strike on Seattle.”

The constructing is about 3,000 sq. ft, with an 18-inch-thick concrete roof and 15-inch-thick partitions.

The primary entrance is a sliding, heavy metallic grate that results in an underground concrete hallway to the principle a part of the ability.

The hallway was designed with many right-angle turns to stop gamma rays from reaching the inside.

There was a upkeep room with a diesel-powered electrical generator, an air circulation system with warmth and air-con, a nicely and pipes that linked to the town water and sewer methods.

Different rooms had been out there to retailer meals or present easy medical care.

There have been two loos with three bogs, a urinal, two sinks and two decontamination showers.

Subsequent to the loos there was a really slender “escape tunnel” that led out to an space close to the street-side entrance.

Partitions had been painted a pale, institutional inexperienced. Freeway noise was audible, however muffled.

Occupants had been solely allowed to carry objects that may “enhance shelter habitability,” drugs and “particular well being meals.”

All meals can be turned over to the shelter supervisor for equitable distribution.

“Normally, survival relatively than consolation would be the major goal,” the 1963 shelter information mentioned.

Animals and pets weren’t allowed.

Which Inexperienced Lake or Ravenna residents had been be sheltered apparently relied on how briskly they might attain the shelter’s door.

When the shelter reached most capability, the shelter was presupposed to be locked and anybody left outdoors was presupposed to be directed to the following nearest out there shelter; nevertheless, there weren’t any.

By the late Seventies, the shelter was used as a district records-storage heart for WSDOT.

The emergency escape tunnel was blocked and the communications gear was eliminated.

“The one one which was ever constructed is the one right here in Washington state,” Williams mentioned. “By the point it received constructed, I believe folks realized it wasn’t actually an awesome concept. Nuclear bombs had been getting so huge (and) with Soviet submarines, the assaults had been going to come back actually fast,” and shelters wouldn’t be a lot use.

By 2022, the shelter has been utterly sealed up with no additional entry.
