Once known as the "Red Bridge," this structure was built in 1876 from timbers milled in Baraboo, Wisconsin and hauled to this location for assembly. A center pier was added in 1927 to support the weight of automobiles. In 1940, the Ozaukee County Board voted to forever preserve this bridge. It is the last historic covered bridge extant in Wisconsin. (A replica covered bridge, the Springwater Volunteer Bridge was built in Waushara County in 1997.)
It appears that some repairs have been performed with pressure treated lumber. This center pier was added in 1927 to support the added weight of automobile traffic.
Prof. Kevin Patrick, of Indiana University of Pennsylvania, says that when a straight road curves slightly, crosses a bridge, then gently curves back to the original alignment, the bridge is a replacement that was built next to its predecessor. That is obvious here, except that the original bridge is extant here.
This plaque is mounted above the south portal. Since it faces the noon sun, it has weathered significantly since its placement in 1955. As a result, most visitors don't even see it.
