The Big Mac Bridge

Though it was officially named the Daniel Carter Beard Bridge (after the co-founder of the Boy Scouts and the Sons of Daniel Boone), the public in Newport quickly began calling this the "Big Mac Bridge" shortly after its completion in 1976. The twin yellow arches of the structure recalled the double "golden arches" of the McDonald's logo in many people's minds. According to Wikipedia, "McDonald's considered opening a restaurant at the base after the nickname caught on, but never went to construction."

I'm not sure why the bridge was painted bright mustard yellow in the first place; perhaps the same "focus groups" were hired to determine its color as with the Purple People Bridge.
