When a family desperately needs a new car during an economic crisis, the style and appearance of that new car do not matter as much as cost and functionality. And those priorities are crucial for two states and the federal government as they continue efforts to replace the Interstate 5 Bridge.
That’s why Monday’s decision by Govs. Chris Gregoire and John Kitzhaber to proceed with a deck truss bridge makes sense. Multiple bridge experts agree the deck truss will be more affordable and less susceptible to construction delays and cost overruns than a cable-stayed bridge or a tied-arch bridge. Because a deck truss bridge in many ways resembles the Glenn Jackson Bridge on Interstate 205, some architects and others complain that the Vancouver-Portland area is losing the opportunity to construct an iconic bridge that would help define the personalities of the cities, the river and the collective communities.
That point is well-taken. We, too, would prefer a cable-stayed bridge whose appearance would draw national and global renown. That would be the best-case scenario. But the states and the federal government are wrestling with worst-case budgets, and the urgency factor (a new bridge won’t get any cheaper) cannot be overlooked. Kitzhaber said his personal preference was a cable-stayed bridge, but that “would not only cost more, it would carry us out of the timing window for federal financing. If we miss this window, we not only put at risk the overall project financing, but also the $800 million in federal funding for light rail.”
So just as a family chooses the reliable, reasonably priced new car over the stylish luxury car, a deck truss bridge makes the most sense now. And although a structure similar to the I-205 bridge does not meet the iconic standard that many people value, other river-crossers have pointed out that such a bridge allows the best views of the mountains and river.
