The Puget Sound Region is famed for our floating bridges and infamous for Galloping Gertie’s collapse. Now we can boast the nation’s fifth-longest suspension bridge. What did it take to span a mile-wide, fjord-like channel and turn more than 47 million pounds of structural steel, enough cable wire to circle the world twice, and nearly 115,000 cubic yards of concrete into a striking and sturdy new landmark?
