Sinkhole opens up above lightrail transit tunnel

A sinkhole that opened up in Seattle’s Ravenna neighborhood Sunday is causing concern for Sound Transit officials.

The six-foot sinkhole was reported near the sidewalk of a home in the 6200 block of 12^th Ave NE, Sound Transit officials said.

The hole is above an area where one of Sound Transit’s boring machines dug a tunnel for the Northgate light rail transit tunnel. The tunnel was built about a year ago.

Sound Transit crews were filling the hole with cement Sunday night.

Coincidentally -- the hole is  situated roughly 4/10 of a mile from where a massive sinkhole opened up on Nov. 12, 1957.

The 1957 sinkhole occurred in the 1600 block or Ravenna Boulevard. It was about 100 feet long, 66 feet wide and 40 feet deep.

The sinkholes are not related.

While there isn’t any structural damage to the house, the residents of the home and the neighboring home have been put up in a hotel as a precaution.

Sound Transit says it will do tests to see if there are any other issues in the area.
