Wabash River
Former Swing Bridge
Vincennes, IN
This is a recent replacement span for the former through truss swing span in the Vincennes River Bridge.
Note that this span looking at the south side goes from the abutment at right across the round pivot pier and on to the second pier in one span. The other spans of the bridge only go from one pier to the next pier.
All of the older bridges on the Wabash up to Terra Haute had swing spans.
