Multnomah County recently selected the construction team for the $895 million Earthquake Ready Burnside Bridge project to replace the 97-year-old span with one that can withstand a major earthquake.

will be the construction team; it’s a joint venture featuring Stacy and Witbeck, Traylor Bros., and American Bridge Co. The team will use the construction manager/general contractor (CM/GC) delivery method and begin work in December.

The team members have extensive experience with CM/GC delivery, construction of technically challenging and signature bridges, and have demonstrated dedication to diversity and equity in both subcontracting and workforce development in previous projects, a spokesperson for Multnomah County stated.

Traylor Bros. has completed more than 135 bridge construction projects, including significant upgrades to Portland’s Hawthorne Bridge, according to the project team’s website. American Bridge has more than 120 years of experience building bridges, including the original Burnside Bridge.

Currently, no Portland bridge carrying regular vehicle traffic across the Willamette River is expected to be immediately usable after a major earthquake. Now, Multnomah County is leading the effort to replace the Burnside Bridge with a seismically resilient one.

The construction team is expected to start demolition and construction in mid-2026. The new Burnside Bridge is expected to open in spring 2031.
