Preparing the Burnside Bridge to survive the Big One
Multnomah County's Earthquake Ready Burnside Bridge Project seeks to ensure our community has a reliable river crossing on a regional lifeline route after a major earthquake.
To take us across the river for another hundred years, the Burnside Bridge needs an upgrade.
The Burnside Lifeline
The Burnside corridor, including the Burnside Bridge, serves as a regional emergency transportation route designated to be operational after a disaster.
Portland Fire & Rescue frequently uses the Burnside Bridge for daily emergency response -- fire, traffic accidents, and medical emergencies. In the event of a major earthquake, a reliable, central river crossing becomes even more critical to Portland’s emergency responders.
Cascadia Subduction Zone Earthquake
Geologically, Oregon is located in the Cascadia Subduction Zone (CSZ), making it subject to some of the world’s most powerful, recurring earthquakes.
