Railroaders know this bascule bridge as Wabash Bridge, currently owned and operated by Norfolk Southern Railway (NS).
The view is south (downstream), looking toward the Fisher Freeway (I-75) / Rouge River Bridge (Scott Hocking photo, 2017).
Ken Borg That bascule bridge is one of eight that was built to this design and one of three that are in Michigan.
