Ferry Street/Thorofare Canal Bridge

The Ferry Street Bridge is eligible for the National Register under Criterion C as a representative example of a continuous concrete-slab bridge. It is also eligible under Criterion A as an example of the evolution of the road commission's bridge design. The East River Road Bridge over the North Hickory Canal, also on Grosse Ile, is eligible for the National Register under the same criteria. According to the Wayne County Road Commission's 1945-1946 annual report, the county maintained '138 modern river bridges over 30-foot span,' plus 'more than 50 bridges on secondary roads which are being gradually replaced as funds become available and as the necessity for their replacement demands.' In the next year, the old township bridge at Ferry Street, an 85-foot Pratt truss, apparently rose to the top of the list, and was replaced with the present structure. The commission's 1946-1947 annual report included a photograph of a similar structure, the Graham Road Bridge over the Rouge River, with the caption: 'This is typical bridge construction for township roads.' Development of the Lodge Expressway (M-10) took most of the commission's energy during this period; the Ferry Street Bridge was one of only three township road bridges built in 1947. The Wayne County Road Commission used the continous concrete slab as a standard bridge plan in the years following World War II, presumably in part to minimize the use of steel, which was expensive and difficult to obtain during this period. The Ferry Street Bridge was designed under the supervision of chief designer Julian C. Mead, who was employed by the road commission from 1921 to 1957.

Ferry Street stretches from the East River to the West River roads on Grosse Ile, north of Grosse Ile Parkway. The Ferry Street Bridge, a 95-foot, four-span, continuous concrete slab, passes over Thorofare Canal east of Meridian, in an exurban residential area. The structure's longest span is 26 feet. The railings of the bridge are solid concrete parapets with an incised horizontal line near the top. White marble bridge plates at the northeast and southeast ends identify the bridge as Job 413 of the Wayne County Road Commission. The 36-foot-wide deck holds a 28-foot-wide roadway; an open expansion joint separates the roadway and the sidewalks along each side. The bridge is supported by three bents which feature square concrete posts with chamfered edges.
