Visit our Online Open House and Survey from September 3 to October 4 to learn more about the alternatives and tell us what you think.

Portland’s aging downtown bridges are not expected to withstand a major earthquake. That’s why Multnomah County is taking the lead on making at least one crossing earthquake ready.

Located in the heart of downtown and on a regionally established lifeline route, it is critical that the Burnside Bridge is still standing after a major earthquake.  A resilient Burnside Bridge will help our community recover after a major earthquake and provide a long-term river crossing that supports our transportation needs for the next century. 

Over 100 options were studied during this project’s Feasibility Study Phase (2016-2018), including tunnels, ferries and other bridge options. From that study, four bridge alternatives (and a no-build or “do-nothing” option) were recommended for further evaluation, which are:

1. Enhanced Seismic Retrofit

2. Replacement: Fixed Bridge

3. Replacement: Movable Bridge

4. Replacement: Movable Bridge with Northeast Couch Connection

Learn about the four bridge alternatives.

Now, the project team is transitioning into another study, called the Environmental Review, that will further study the benefits and drawbacks of these remaining alternatives. At the end of this study, we will decide which alternative to build. That is where you come in! It is important that the community helps us select the best alternative.

Environmental Review

During the Environmental Review phase, we will prepare an Environmental Impact Statement, or EIS. This is federally required by the National Environmental Policy Act, or NEPA.

This is an important phase of project planning where we take a good, hard look at the project alternatives and assess their benefits and impacts. This helps us make an informed decision about what to build. It guides us in understanding the tradeoffs and deciding which alternative best meets the needs of the project.

During the Environmental Review phase, we look at how each alternative, including the No Build alternative, would affect social, cultural, built and natural resources. We also look at cost, ease of building, ability to survive an earthquake and other factors.

The EIS will include public input gathered throughout the study. During the month of September 2019, we are asking the public to review and comment on important elements of the study, including:

As the environmental review phase continues, we will ask for input on choosing a preferred alternative.

Environmental review is a long process. The goal is to choose a single alternative that best meets the community’s needs. Then we’ll be ready to get to work designing and building an Earthquake Ready Burnside Bridge.

Schedule

Environmental Review Phase – 2019-2021 

Key Milestones:

  • Summer/Fall 2019 – share information and get input on items to consider in the study

  • Summer 2020 – share findings from the environmental study and ask for community input on the preferred alternative

  • Winter 2020/2021 – publish the Draft Environmental Impact Statement (DEIS) and get community input

  • Fall 2021 – a Final Environmental Impact Statement (FEIS) and a Record of Decision (ROD) will approve the preferred alternative that can then move into the Design Phase and then Construction

Design Phase -  2022-2024

Construction Phase- 2024-2029

Burnside Bridge Maintenance Project

Built in 1926, the Burnside Bridge is an aging structure requiring increasingly more frequent and significant repairs and maintenance. Multnomah County is conducting maintenance through 2019 to keep the Burnside Bridge operating and safe until a long-term seismic solution is identified. The maintenance includes surface, structural, mechanical and electrical work that will occasionally affect bridge and river traffic. More information on the maintenance project can be found here.
