Not sure where my original post went but anyway, Boeing has private property signs all over the bridge so I guess it must be theirs. They have armed officers now on the bridge at certain times turning cyclists around and the first time I noticed them, it looked like they were getting ready to arrest a guy who was yelling at them. I don't know about anyone else but i just want to ride and there's other, easier ways to go without having to bother with the bridge. But in answering your question, Yeah I'm pretty sure that's Boeing's bridge and it looks like it's no longer open to the public.
