The Sixth Street Bridge was designed and built in 1886 by the Ohio-based Massillon Bridge Company for $31,000. The westernmost truss was shortened in 1921 when a canal along the river bank was filled in.[2]
The bridge faced demolition in 1975, but was saved through the efforts of concerned citizens. The following year, the bridge was designated a Michigan State Historic Site (MSHS), and listed on the National Register of Historic Places. An MSHS informational marker was erected in 1981.[2] The bridge is also listed on MDOT's Historic Bridge Inventory.[3]
The bridge underwent significant renovation in 2012, funded with a $1.8 million federal grant and $472,000 from the Downtown Development Authority.[5]
Design
The bridge is 536 feet (163 m) in length, consisting of four parallel cord through Pratt trusses made of wrought iron.[2] The roadway is narrow at 19 feet (5.8 m) wide with two lanes.[2][5] Along each side is a 6-foot wide (1.8 m) sidewalk with ornamental railings. The piers and abutments are masonry and built of local Grand River limestone. The Sixth Street Bridge is the longest and oldest metal truss bridge in Michigan.[2]
