Stakeholder Update

​The Stakeholder Update is a semi-regular newsletter of the Oregon Department of Transportation, which provides news on transportation policy and programs to key stakeholders.

September 2015

The health of Oregon’s bridges directly affects the health of our economy and job market. The latest bridge condition report from the Oregon Department of Transportation puts a dollar figure to the cost to Oregon’s economy if the state’s bridge system isn’t adequately maintained: In the next 20 years, Oregon could forfeit $94 billion in production and 100,000 jobs if action isn’t taken. The good news: If we act soon, Oregon still has time to keep our bridges healthy.

Dig into bridge data

Use our bridge data visualization to learn more about how old our bridges are, what condition they’re in, and who owns them. You can look at statewide data, pull up a single county, or drill down to an individual bridge.

What’s below the deck? Barges, cranes, dive teams and more

Check out our YouTube videos of bridge inspections, underwater and in the air. See what it takes to keep Oregon bridges safe and sound. While you're at it, explore our Flickr page to see Oregon’s bridge conditions up close.

5 things to know about Oregon's bridges

To replace each state highway bridge on a 100-year cycle requires replacing an average of 27 bridges each year; Oregon taxpayers fund the replacement of an average of three bridges per year. Bridges should normally receive major maintenance every 30 to 50 years; current bridge funding covers major maintenance only once every 100 years. At the current rate of replacement, state highway bridges will have to last more than 900 years on average.

What about “The Big One”?

Because most Oregon bridges were built before modern seismic standards were in place in the 1990s, most bridges in western Oregon would collapse or be rendered unusable in a major Cascadia Subduction Zone earthquake. Highways would be closed for months or years, rendering disasterresponse difficult and preventing Oregon’s economy from bouncing back.

A comprehensive bridge investment strategy that replaces bridges at the end of their lifespan with new structures and undertakes seismic retrofits on otherswould allow the state’s highways to recovery quickly after a quake so they can help with post-earthquake response and recovery.
