Bridge Documentation

This bridge no longer exists!

This bridge is an example of a historic bridge superstructure for which preservation is feasible and prudent but yet the bridge could potentially be at risk for demolition or collapse due to the failure of a substructure. Floodwaters washed out the dirt around the concrete abutments, and one way or another, the feet of the bridge are no longer resting on anything, and so other parts of the bridge are bearing more weight than they should. However, the bridge has remained standing in this condition, and it remains in a condition where there really is nothing about the superstructure that makes preservation impossible, or even difficult. The truss bridge superstructure of this bridge is in decent condition. There are isolated areas of severe deterioration, most notably at the base of the endposts, but this is a common trouble spot and is easy to repair or replace/replicate as part of a comprehensive rehabilitation. Another area of deterioration, the bottom flanges of the floorbeams, could also be repaired or replaced easilly. The solution is simple: lifting such a small bridge off of its abutments, reconstructing the abutments, rehabilitating the truss, and placing it back into service for light vehicular traffic would be an easy preservation project. Alternatively, the truss could be relocated and used elsewhere, perhaps on a non-motorized trail, or on a snowmobile/ORV trail.

This bridge is historically and technologically significant as an early (the bridge stylistically dates to roughly between 1910-1925) and unaltered example of a truss bridge that uses bolts instead of rivets for all connections, and it is one of the only examples of a historic truss bridge with bolted connections in the entire state of Michigan, along with the other two truss bridges in Mason County. The bridge retains excellent historic integrity. All bolts on the connections appear to be original, and original lattice hub guard railings remain on the bridge as well. It is unclear why Mason County has three truss bridges with bolted connections while elsewhere in the state this design is nearly unheard of. Of the three in the county however, this bridge is perhaps the most significant on account of it being the longest span and its good historic integrity.
