This steel stringer bridge is a standard mid 20th Century steel stringer bridge in Michigan, and it retains attractive Type R4 railings. The bridge is noted for its curved design which includes superelevation. The stepped
design of the top of the abutments, which changes the elevation of each stringer slightly is how the superelevation is accomplished. Among bridges old enough and with enough historic integrity to be listed on HistoricBridges.org, few
display a curved design with superelevation, so this bridge stands out as uncommon among those bridges featured on HistoricBridges.org.
