BNSF/NP 1911+1928 Bridges over Duwamish River in Seattle, WA

(1911 Bridge Hunter, 1928 Bridge Hunter, 3D Satellite)

While looking at a satellite map for the BNSF/GN bridge over the Lake Washington Ship Canal, I spotted this bridge on the satellite map. And then within 24 hours I saw this posting.

Hello fellow bridge and tunnel admirers I have just acquired the Walthers bascule bridge. Reading the blurb it stated that this model is based on the real thing crossing the Duwamish river in Seattle Washington. Apparently it is still in use by BNSF and I was wondering if anyone had a photo of a bascule bridge crossing the Duwamish they could share?🤔🤔. I want to maybe give it that look, anything will help. Cheers🤓

The Bridge Hunter pages for this bridge taught me that Strauss' early designs put the lift machinery on the end of the top cord of the movable span and his later designs moved the machinery to the stationary counterweight tower. The Strauss bridge in Ashtabula, OH, is an example of an early design that never got converted to the later design. This bridge was converted in 1928. Judging from the platform still remaining at the end of the top cord of the span on the close by Salmon Bay Bridge, I presume it is another converted bridge.
