San Francisco, the "city by the bay," is known for its incredible bridges, including the elegant and impressive San Francisco-Oakland Bay Bridge. This bridge is remarkable in that it is the longest high-level bridge in the world, spanning over eight miles. In 1955, the American Society of Civil Engineers declared the Bay Bridge the Seventh Wonder of the World. This photograph captures the majestic Bay Bridge on a clear summer night -- a rare scene in a city known for its fog. The Embarcadero street lights cast an ethereal glow on the rustic pylons in the foreground, contrasting beautifully with the string-of-pearl lights crowning the bridge and the backdrop of an illuminated horizon showing off the distant lights of Oakland.
