Richmond-San Rafael Bridge, photo by Harold Davis. View this image larger.
At one time one of the longest bridges in the world, the John F McCarthy Memorial Bridge is a double cantilever structure stretching across the San Francisco Bay from Richmond to San Rafael. Certainly not the most glamorous bridge across the Bay, the snake-like twist in the structure adds visual interest, particularly under cloudy night skies.
