Proposed Columbia River Crossing - too high or too low?
It really doesn't matter because the question that needs to be asked is how the bridge proposal could have gotten this far without resolving these questions? The Oregonian notes: "The current bridge is not high enough for the Coast Guard. But a higher bridge may be unacceptable to the Federal Aviation Administration, whose charge is to protect the air space of Portland International Airport and Pearson Field in Vancouver." [Proposed Columbia River Crossing is a bridge too low, Coast Guard says].
