This bridge got its name from a Native American legend. When the mighty Columbia River separated two chiefs, the gods created this natural rock bridge that actually does not stretch the full span of the river. Geologic findings show a more scientific reason for the bridge-like formation and narrow in the river. Either way, the now man-made, toll bridge is something to behold. The beauty and breadth of the Columbia can be taken in by driving across slowly or at a lookout spot on the Washington side.
