was built high enough to where it could remain stationary and still allow small vessels to pass beneath it. Because of the amount of traffic that travels across it, the bridge has deteriorated in recent years.

Harbin Drive Bridge

The Harbin Drive Bridge is a much smaller bridge at only 45 feet (13.7 m) long and 27 feet (8.2 m) wide. It carries the sparsely traveled Harbin Drive over the Silver Creek Canal, which drains into the Huron River. It is located just north of the Jefferson Avenue Bridge, and the two are connected by a continuous railing. The Harbin Drive Bridge was actually constructed a few years earlier than the Jefferson Avenue Bridge, although this exact construction date is unknown. Harbin Drive is a gravel road that connects a few residential dwellings on a narrow island in the river.
