Posted by zac on Sun Mar 29 18:50:28 2026, in response to Re: A World First (?) Opened Today, posted by AlM on Sun Mar 29 17:47:00 2026. There are 3 in the Seattle area. This is the third but isn't new, just new for rail. I biked many times over the original I-90 bridge across the lake to Mercer Island and on to Bellevue/Redmond/Sammamish. They built a second span for it, and then when they went to reconstruct the existing bridge it sank in a storm.Because they used a lot of water during construction, and they did not want that water in Lake Washington, they stored it in the open pontoons. Well, that was an absolute genius move. During a storm, the open pontoons took on lake water, and when one sank it pulled the rest of them down with it, and the bridge too. WTF did they think would happen? They are there to hold up the bridge by keeping the water OUT of them. So the bridge with the rail is the third bridge to be built on that site. There is the 520/Evergreen Point bridge just north of it, and Hood Canal is across Puget Sound. And that is another story. In 1979 I think, there was a storm that sank that bridge too. The problem with Hood Canal is that it rises and falls with the tides. And then we have Galloping Gertie, the Tacoma Narrows Bridge. And the West Seattle Bridges, and I think one more. Seattle/Washington State don't have a great track record with bridges. |
