Gehry's approach to the GMB's wateriront setting is at once playful and imposing. the museum's entire structure seems to stretch indulgently along the bank of the Nervion River, and to ramble into unexpected places--a portion of the building boldly slides underneath La Puente de la Salve, a steel suspension bridge which cuts across the site. Gehry further engages La Puente se la Salve into his design with an elaborate, sculpturelike tower, the kind of structure that he calls a "high reader." the tower has no function other than visual punctuation.
