Design
The first bridge on the site was distinguished for its construction at the snout of the Nisqually Glacier; this made the Nisqually Road "the first road in America to reach a glacier." However, the siting just below the massive glacier led to the destruction or heavy damage to four subsequent bridges by glacier floods. The present high-level bridge, 600' below the old bridge site, was designed to survive the extreme conditions sometimes encountered at the crossing.
