Concern #1: Phase one is projected to cost $3.913 million. Is phase two (building new foundations and restructuring the intersections around the new bridge) really going to cost only $1.6 million, or is the figure of $5.5 million a low-cost estimate?
Concern #2: They're removing the old Sauvie Island bridge because it has been declared unsafe for traffic in its current location. Has anybody done the engineering to show that it's safe for pedestrian traffic at its new location? The foundations will not be level without a significant amount of new engineering (will this cost less than $1.6 million?), which will put unequal and unanticipated stress on the structure. Furthermore, full saturation pedestrian traffic puts a higher load on a bridge than full saturation car traffic. If it can't support cars, will it support a marathon?
Concern #3: How much longer is the Sauvie Island bridge expected to last? If we pay less for it now, as Sam claims, how soon will we be just be paying for a new bridge anyway? If bridge prices are going up as Sam claims, will we be paying five million now and twenty million in fifteen years once this one falls apart, or can we just pay the eight million he says it will cost and not have to worry?
