county received U.S. federal funding sufficient to begin immediate work on a replacement. On July 19, 2012, Multnomah County commissioners approved a $299 million design for a new bridge. On July 19, 2012, a final design was approved by Multnomah County commissioners. The design is a steel deck arch bridge with pedestrian and bicycle lanes on both sides. Construction was funded with $136 million from the county (raised from a $17 annual vehicle registration fee), $33 million from the federal government, $35 million from the state, and $84.5 million from the city of Portland. Clackamas County was originally to provide some funding due to the bridge’s use by many residents of that county, but that plan was later rejected by voters. On January 19, 2013, the 6.8-million pound bridge was moved onto temporary steel supports by contractor Omega Morgan. The moved bridge, known as a shoofly bridge, served as a temporary span until the new crossing opened. After more than three years of use on temporary supports, the old bridge closed to traffic permanently on February 25, 2016, and the new bridge opened to traffic on February 29, 2016. In between, on February 27, an opening celebration event took place on the new span with access to pedestrians and cyclists only. Crews began demolishing the original railings and bridge deck once the old span closed, with the process completed in May 2016. The steel trusses were then cut into pieces and lowered onto barges using hydraulic jacks, and the temporary steel supports were dismantled. Design The new Sellwood Bridge stretches a total of across the Willamette River. The deck arch design’s longest span is long and rests on a total of two piers in the water. There are a total of three arches carrying the wide span. The deck carries two lanes of traffic, bicycle lanes in both directions, and sidewalks on both sides. The architect for the new Sellwood Bridge was Safdie Rabines Architects with T.Y. Lin International serving as Prime Consultant for Final Design. The final design reduced the bridge footprint significantly from early concepts, lowering project costs and minimizing environmental disturbances. The final bridge design is also based on contemporary seismic codes and satisfies both a 475-year return period event for operations and a 975-year return period for safety.
