Today, Galloping Gertie is known as “the world’s largest man-made reef.” An abundance of marine life thrives among the massive girder sections, concrete rubble and half-mile of roadway submerged beneath the Sound. It is a thriving ecosystem, and anemones, sea stars, mussels, barnacles, octopi, salmon, sea lions, wolf eels, sea lance and diving birds make their homes nearby.
