Lilley Road/Lower Rouge River

As a well-documented example of a 1920s pony truss, this bridge is eligible for the National Register under Criterion C. Under the provisions of the McNitt Act, Wayne County took over responsibility from Canton Township of two narrow, dilapidated, steel bridges along Lilley Road in 1933. One bridge crossed the main channel of the Lower Rouge River; the other spanned an overflow channel about 400 feet away. The county road commission immediately embarked on a project to improve the crossing, first significantly changing the channel to require only one structure. They then installed a skewed truss, which had just been removed from the Telegraph Road crossing of a branch of the Rouge River, north of Warren Road. The truss was no longer suitable for Telegraph Road, which was being widened. It was originally fabricated and erected in 1923-1924 by the Massillon Bridge and Structural Company of Massillon Ohio. County crews did related site work on Telegraph Road, resulting in a total expense of $20,885 on the project during that fiscal year. In the same period, the county erected 'practically a duplicate' pony truss on Telegraph Road over the Rouge River, about 3 miles to the south. The latter bridge is pictured in the road commission's 1923-1924 annual report. The superstructure, which appears essentially identical to the Lilley Road Bridge, has a cantilevered sidewalk and railings; concrete balustrades with urn-shaped spindles edge the approaches. When the Telegraph Road Bridge was moved to Lilley Road in 1933, its historical integrity was maintained. When the Lilley Road Bridge was surveyed in 1995, a contractor had sandblasted and primed the superstructure, and was in the process of repainting it.

Lilley Road, which runs north-south, passes over the Lower Rouge River just north of Michigan Avenue (US-12). The road is in western Wayne County, about midway between Detroit and Ann Arbor. Once rural, the area is now experiencing residential and other development, probably stimulated by Interstate 96 not far to the east. The Lilley Road Bridge is a 90-foot, steel, 8-panel, camelback pony truss comprised of the following elements: upper chord: back-to-back channels tied by X-lacing (top and bottom); lower chord: channels with battens; verticals: built-up I beam; diagonals: paired angles with V-lacing; railings: bars riveted to angles; bottom lateral: paired angles; new I-beam stringers; built-up I-beam floor beams riveted to superstructure; steelmaker's mark: Carnegie USA. The 44-foot-wide deck carries a 27-foot roadway. Sidewalks rest on metal brackets outside of the trusses. The substructure is comprised of concrete abutments and straight wing walls.
