The Sellwood Bridge is a deck arch bridge that spans the Willamette River in Portland, Oregon, in the United States. The current bridge opened in 2016 and replaced a 1925 span that had carried the same name. The original bridge was Portland's first fixed-span bridge and, being the only river crossing for miles in each direction, the busiest two-lane bridge in Oregon. The Sellwood Bridge links the Sellwood and Westmoreland neighborhoods of Portland on the east side with Oregon Route 43/Macadam Avenue on the west side. At its east end it leads to Tacoma Street. The bridge is owned and operated by Multnomah County. The original span of 1925 was a steel truss bridge, while its 2016 replacement is a deck-arch-type bridge. Original bridge Designed by Gustav Lindenthal, the first bridge opened on December 15, 1925, at a final cost of $541,000 (equivalent to $6.9 million in 2011). It was long with of vertical waterway clearance. It had four continuous spans, all of Warren type. The two center spans were long, and the two outside spans were each. The girders from the old Burnside Bridge (built in 1894) were reused at each end. The two-lane roadway was wide, and there was a sidewalk along one side. In the 1960s, a rebuild of the bridge was proposed as part of an east–west freeway that would follow Johnson Creek Boulevard between I-5 and I-205. Deficiencies and replacement In the 2000s, discussions began to intensify over the bridge's condition, which had been deteriorating since the 1960s. Upon discovery of cracks in both concrete approaches in January 2004, the weight limit on the bridge was lowered from 32 tons to 10 tons. This caused the diversion of about 1,400 daily truck and bus trips, including 94 daily TriMet bus trips. Over the few years that followed, there was debate on whether the bridge should be replaced, repaired, closed altogether, or closed for automotive traffic (but left open for pedestrians and bicycles). In April 2005, Bechtel gave Multnomah County an unsolicited plan to replace the bridge through a public-private partnership. Discussions over possible replacement of the bridge also considered changes that a new bridge might incorporate in order to make the structure more usable for cyclists and pedestrians than the bridge it would replace. The 1925 bridge included no designated space for bicycle traffic, which had grown in more recent decades, and with only a
