Oregon Slough Railroad Bridge, Portland

The Oregon Slough Railroad Bridge, also known as the BNSF Railway Bridge 8.8, is a swing-span, through truss bridge in Portland, Oregon, United States. Currently owned and operated by BNSF Railway, it crosses an anabranch of the Columbia River known as North Portland Harbor and historically as the Oregon Slough. The bridge's northern end is on Hayden Island, which, along with Tomahawk Island, forms the north shore of the channel. Completed in 1908, the two-track bridge is one of only two swing bridges surviving in Portland, which once had several bridges of that type, both for road and rail traffic. The only other remaining swing bridge in the Portland area is another rail-only bridge on the same line, BNSF's nearby Bridge 9.6, spanning the Columbia River. ()
