Meridian Bridge

Posted May 14, 2008, by Randy Brush

I heard newspaper since May 11, 2008. A ten ton load limit has been placed on the Meridian Bridge at Yankton, South Dakota. All truck over ten ton use other bridges at Vermillion or Springfield over Missouri River. It are fair condition. Thank you.

Missouri River Bridge

Posted September 12, 2007, by Robert L. Elder (Bass-tbn [at] ku [dot] edu)

Construction of a new bridge began in July of 2007. The new bridge, known as the "Discovery Bridge" in honor of Lewis and Clark will be built two blocks west of the current bridge. This new bridge will provide a better alignment for US 81 and large trucks will not longer need to navigate two sharp turns in Yankton. Supposedly, the old bridge may be converted into use as a pedestrian bridge.
