History & significance

The Sulphur Lake Bridge (Bridge 4667) was built in 1927 to carry Trunk Highway 19/71 across Sulphur Lake in rural Honner Township, Redwood County. The 169-foot bridge has a 117-foot riveted Camelback through-truss main span. Concrete-slab approach spans are contained within the abutments, which have concrete parapet railings. Since September 2010, the bridge has been closed to vehicular traffic but continues to carry pedestrians, bicycles, motorcycles, ATVs, and snowmobiles.

Bridge 4667 is significant for its association with the Minnesota Highway Department’s bridge building and highway improvement efforts in the 1920s, as well as being a representative example of the Camelback through truss, an unusual type in Minnesota.
