This is Port Huron's largest and least-opened 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 upgraded the equipment to modern hydraulics. You can see these from the northeast quadrant around the bridge, where you can peek through a fence and see some of the mechanics. 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.
