Th bridge has been closed to all vehicle traffic since early July 2015 following damage to the abutments caused by flooding on the Cuivre River. The water was touching the bottom of the bridge. You can still walk on it.

Bridge was closed to all traffic 03/09/2008.

Appears car accident on the North side of bridge severely damaged the guard rail leaving a large gap on that approach. From what I saw of most of the railing it wouldn't take much of an impact to just about tear the rail off clean. Most of the railing was barely attached because of rust damage. Bridge is in very poor shape.
