In Worst-Case Quake Scenario, Half Of Oregon’s Bridges Could Collapse

As Oregon comes to terms with growing evidence that an extremely large earthquake is likely to strike in coming decades, transportation authorities in the state said on Monday that half the state’s bridges could collapse when "the big one" strikes.
In a worst-case scenario, a magnitude 9.0 quake would destroy dozens of bridges and overpasses on U.S. Highway 101, the major north-south road along Oregon’s coast, as well as those on every significant road connecting isolated coastal communities with inland areas, Don Hamilton, a spokesman for the Oregon Department of Transportation, told Reuters.
