Tristan,
Thanks for the information on these Willamette River crossings. I keep meaning to schedule a kayak trip to these structures, but time never seems to be on my side.
Since there's very little information and no pictures of this bridge on here yet (or of the parallel former SP swing span one beside it because they're nearly impossible to photograph) I would just like to add; this bridge was originally built by the Oregon Electric, an intercity trolly company in the early 20th century. Most of OE's rails have long been ripped up after the company closed, but this part of their former line (which directly parallels the ex-SP [now UP] Brooklyn mainline from Eugene to Harrisburg and then diverges)survived as a competing freight line. It is currently owned by BNSF and leased to PNWR. According to a Register Guard archived article, the lift span was never fully operational which prevented potential steam boats from reaching Eugene via the Willamette. I've included two pictures of the bridge I was able to take from the parallel bridge on Amtrak Cascades #507. (photo date: 6/5/2013)

Is there a way to view the Register-Guard article about this rail line and bridge?
