Earthquake Ready Burnside Bridge project logo

Portland’s aging downtown bridges are not expected to withstand a major earthquake. That is why Multnomah County is taking the lead on making at least one crossing earthquake ready. Located in the heart of downtown, the Burnside Bridge is a regionally established lifeline route across the Willamette River. 

    Project Status

    The Feasibility Study's recommendations were approved by the Board of County Commissioners in November.

    River User Survey

    Multnomah County is conducting a river user navigation study as it evaluates alternatives for a Burnside Bridge retrofit or replacement which could survive a major earthquake.

    September Outreach

    During September 2018, two in-person open houses and an online open house were held to get public comments on the range of alternatives proposed for the environmental review phase.  The outreach period has ended. The project team shared the results with the Board of County Commissioners on November 1, before they voted on the recommended range of alternatives.

    Burnside Bridge Maintenance Project

    We are also doing maintenance on the Burnside Bridge through 2019. The Burnside Bridge Maintenance Project will repair and improve the bridge to keep it safe and working for another 15-20 years.
