Overview

The Draft Environmental Impact Statement comment period is now closed. This site is available for viewing purposes only and contains information and related documents pertaining to the Draft EIS.

Multnomah County is leading the Earthquake Ready Burnside Bridge (EQRB) project to provide rapid and reliable emergency response, rescue and evacuation after a major earthquake, as well as enable post-earthquake economic recovery. In addition to ensuring that the crossing is seismically resilient, the purpose is also to provide a long-term, low-maintenance and safe crossing for all users.

As part of the federally required process by the National Environmental Policy Act, or NEPA, the project team, working with the Federal Highway Administration (the federal lead agency), prepared a Draft Environmental Impact Statement, or EIS. The Draft EIS describes the range of alternatives being considered, their impacts, and potential ways to mitigate those impacts. It also recommends a preferred alternative.

Thank you to those of you who shared your input on the Draft EIS and analysis! The Draft EIS materials will continue to be available through this site and at www.burnsidebridge.org in the future.

What is being proposed?

What is being proposed and why? 

The primary purpose of the EQRB Project is to create a seismically resilient Burnside Street lifeline crossing of the Willamette River. The Bridge would remain fully operational and accessible for emergency responders, cars, trucks, buses, bikes and pedestrians immediately following the next Cascadia Subduction Zone (CSZ) earthquake. None of the current bridges in downtown Portland are expected to be usable after this type of seismic event.

There are five specific needs the project would address. These include the need for:

  • A Seismically Resilient River Crossing and Lifeline Route
  • Post-Earthquake Emergency Response
  • Post-Earthquake Recovery
  • Emergency Transportation Routes and Seismic Resiliency as Stated in Plan and Policy Directives
  • Long-Term Multimodal Travel Across the River

Technical Report Topics

The Draft EIS summarizes the relevant natural and built environment along with social and cultural resources that would be potentially affected by the project. The document compares both the benefits and impacts that would be expected from the different alternatives and options being studied.

A list of all the technical report topics are shown in the table below. You can access the level of detail that is right for you by following the links to a brief summary, the full technical report, or by referencing the chapter and page number in the Draft EIS.
