The Earthquake Ready Burnside Bridge project task force has recommended a new, $825-million long-span bridge to replace the Multnomah County-owned structure that crosses Portland’s Willamette River.
The task force studied over 100 options, including tunnels, ferries and bridges, during the 18-month process to quell seismic concerns issues on the 94-year-old, 1,382-ft-long bascule bridge. The other three final options included an enhanced seismic retrofit and two short-span alternatives. All bridge options include movable components.
