Meridian Bridge in Yankton, SD at twilight.

The Meridan Highway Bridge is a bridge that formerly carried US Route 81 across the Missouri River between Nebraska and South Dakota. The Meridian Highway Bridge connects Yankton, SD with rural Cedar County, NE. The Meridian Bridge is a double deck bridge, with the top level having carried traffic into South Dakota from Nebraska, and the lower level having carried traffic into Nebraska from South Dakota. This bridge was closed and soon underwent conversion to pedestrian/bike use after the new Discovery Bridge was opened to traffic in October 2009. In November 2011 it opened for recreational use. Hiking, biking, running or walking across the bridge is a popular outdoor activity in the Yankton area.
