BNSF to replace SEA - Evrette bascule bridge

[blue streak 1]

Bridge is going to be replaced with a lift bridge.  Trunion bearing going bad.

  It seems that in most drawbridge replacements that a lift bridge is the preferred way that RRs are going.  Of course local conditions may prohibit that alternative.  Have read that lift bridges are more earthquake resistat than bascule.  Swing bridges who wants a center pivot ?

Vertical lift bridges are preferred when there is a skew to the river crossing, such as the South Branch Bridge in Chicago.  I've also seen them used to replace bascules when a wider river clearance is needed, like the now-abandoned CWI bridge over the Calumet River.

And they will spend 2 years getting approvals to replace something that is already there. I know it's next to the old one, but still, 2 years to say OK, you can start now.

Here is some further information about the replacement of the Salmon Bay Bridge: http://mynorthwest.com/1141666/salmon-bay-railroad-bridge/

It contains some old pictures.

Been through both of these on my boat, esp. the Everette one. It always seemed so low that I would call for it to open. Then got braver learned to read the clearance indicator.  But it was more fun to call. LOL

Bob: Army Corps calls the shots. Unfortunately the USACE has to put up with an awful lot of NIMBY/BANANA know-nothings through the whole process as public input.
