One of the more unique items to be found out in the East County of San Diego is a bridge that is not connected to a road, and at times, does not cross water. The Sweetwater Bridge was built in 1929 to bridge the Sweetwater River, and at the time connected both ends of Highway 94. While it may appear imposing at four hundred and sixty feet in length, and twenty-two feet in width, it was in actuality, a narrow bridge in 1929, and a narrow bridge through its eventual retirement in 1987. In 1987, the road was re-routed slightly and a new, modern bridge was built right next to it on Highway 94.
