Getting to the IBR Solution

Developing a safe and equitable solution for future generations...

Your feedback matters! Combined with stakeholder, advisory groups and partner input, your suggestions will contribute to identifying a new multimodal bridge replacement solution that meets the transportation needs of the region – now and for future generations. View the stations below to learn where the program is in the planning process and take our online survey to share your feedback. Your input will help guide the decisions to identify a bridge replacement solution that meets everyone’s needs.

The Interstate Bridge is located near the Cascadia Subduction Zone, a 620-mile-long highly susceptible earthquake field. Learn more about how a major seismic event could affect the bridge.

Located between Portland, OR and Vancouver, WA the Interstate Bridge is a vital connection that supports  local jobs and families, and is a vital trade route for regional, national and international economies.

I-5 is the most significant freight highway on the West Coast, linking regional, national and international markets. Learn more about why replacing the Interstate Bridge is essential.

Design Options

Fact vs Myth

Myth: Why can’t you just retrofit or replace other regional bridges using the money from the Interstate Bridge Replacement program? Wouldn’t that be a more prudent use of taxpayer dollars?

Fact: There is not one giant pot of money for the IBR program that can be used for other purposes like retrofitting bridges around the NW Oregon and SW Washington region. Funding for construction will come from a variety of sources, including state and federal transportation funding and tolling. All of these funding sources, whether they are dedicated by the state legislatures or competitive grants, must be approved specifically for the IBR program and must be used to address the transportation problems identified.  

Even if it were possible to divert funding allocated to the IBR program, the need for a local and regional transportation lifeline able to withstand a significant earthquake would remain. By replacing the Interstate Bridge with a new seismically resilient multimodal solution, the IBR program would contribute to seismically updating the regional corridor along with improving transit options and reducing safety and congestion issues on Interstate 5.

Myth: The Interstate Bridge Replacement program is nothing more than an expansion of the Interstate 5 freeway.

Fact: The community has told the IBR program that a safe, reliable transportation system with a variety of multimodal choices is important to them. The program is working within the context of what already exists to make multimodal travel safer and more efficient for all. To address existing safety and reliability concerns, the program is looking at interchange improvements and the potential addition of auxiliary lanes. Three through lanes exist now across Interstate Bridge and on Interstate 5 within the program area. The potential addition of auxiliary lanes, which separate through traffic from traffic entering or exiting the highway, would improve safety and help relieve congestion.

There is currently limited capacity for low/no emission travel such as walking, biking, and rolling. Modal choices – including high-capacity transit and active transportation – are critical for advancing more efficient movement of people and goods across the Columbia River. Buses experience the same safety and efficiency problems as commercial freight haulers and automobile users and are often stuck in traffic congestion. A dedicated guideway for high-capacity transit would help mitigate this problem.

Further, people wanting to walk, bike, or roll across the Interstate Bridge are forced to share a four-foot-wide path that is located right next to vehicular traffic. The inclusion of a wider shared-use path that is separated from vehicular traffic is a key component of any new bridge that would be constructed.
