Narrative Description Main span number: 1 Main span length: 90 Structure length: 91 Roadway width: 20 Structure width: 26 Constructed in 1921-1922 from a MSHD standard design, the structure is comprised of a pair of 90 foot arched concrete through girders that rest on angled concrete brackets cantilevered from the skewed concrete abutments. A dozen concrete floor beams span between the two girders; these are cast integrally with the 20 foot wide concrete deck. The arched girders feature typical MSHD detailing, with spandrel walls punctuated by five small arched cutouts aligned over a series of arched recessed panels. The lack of corbeled bulkheads at the girders' ends illustrates the bridge's early construction. Although the Lincoln Road Bridge suffers from severe concrete spalling and Armco guardrails have been installed at the approaches, it retains a relatively high degree of structural integrity.
Statement of Significance The Michigan State Highway Department first developed plans for a long-span concrete through girder bridge with arched girders on cantilevered brackets in the 1921-1922 biennium. "These designs have curved top chords and bottom chord brackets," MSHD reported in it Ninth Biennial Report, making them suitable for relatively long-span applications. The first curved-chord girder was a 90 foot span built in 1922 over the Raisin River at Tecumseh. This was followed in the 1920s by a series of curved girders used in single-span or multiple-span configurations. Among the earliest of these new bridges was the span that MSHD designed in 1921 for the Pine Creek crossing in Gratiot County. The Lincoln Road structure, like the Tecumseh Bridge, featured a 90 foot span. Designated Bridge File Number 291402, it was part of construction on the state reward road that extended along the western edge of Gratiot County. Walter Willets was awarded the contract to build the bridge in October 1921; he complete it the following year for $18,186.15. Since its completion, the Lincoln Road Bridge has functioned in place, essentially unaltered. With its 1921-1922 construction date and its 90 foot span, it is today noteworthy as one of the earliest and longest remaining examples in michigan of the MSHD designed, arched through girder.
