This is Port Huron's largest and least-opened highway bascule bridge. It is larger because it crosses the river at an angle, although the structure's bascule span is not skewed. All three of Port Huron's bascule bridges operate many times a day in the summer, but 10th Street opens less because it is the furthest inland from the St. Clair River. Boats that dock between 10th Street and St. Clair River don't need to pass under this bridge.

This bridge was built during 1956-1958 and it replaced a gorgeous pin connected swing bridge that featured ornate railings and deck plate girder approaches.

The renovations made to this bridge in 2002 upgraded the equipment. You can see some of this from the northeast quadrant around the bridge, where you can peek through a fence and see some of the mechanics of the tail lock. The renovations should not be called a restoration however, since the original historic railings were removed as part of the work. The end result was a severe loss in the beauty and historic integrity of the structure. The bridge was originally designed with Michigan State Highway Department's attractive type R4 railing. During rehabilitation, sidewalk cantilevers were also removed and replaced. The bascule girders and bridge tender house retain original design however. The previous bridge at this location was a swing bridge. The July 31, 1897 issue of The Engineering Record stated that a contract for the 10th Street Bridge was awarded to Groton Bridge Company of Groton, New York for $19,300, which may refer to this bridge.
