Geocache Description:

A couple of rare bridges in Ramsay, MI. A MUST SEE. There is a paved / hardpack trail right to it, but the search could be gnarly.

The keystone bridge, rising 57 feet above the Black River in the Upper Peninsula town of Ramsey, Michigan was built in 1891 by the Chicago and Northwestern Railway Company, and is constructed of limestone quarried form Kaukauna, Wisconsin. A series of arches, each with a center keystone at the top, locks the entire structure. This is one of the largest known stone arch bridges in Michigan and It is one of the few arch bridges of this type in existence. Thus, it is one of Michigan's more important historic bridges. It is most noteworthy for its tall height, which makes it a very impressive structure. It retains excellent historic integrity, and the overall integrity of the structure appears good.

The keystone bridge is next to the equally significant and impressive Ramsay Bridge. The Ramsay Bridge is an impressive example of a concrete girder bridge, as it sweeps over the small valley of the Black River. Such use of the concrete girder bridge was not often seen in Michigan; concrete girders were generally used for smaller crossings that did not have a valley to them. The bridge is significant as the largest remaining example of a straight chord through girder bridge in Michigan. Unfortunately, the bridge has not been maintained and serious concrete spalling has marred the beauty of the structure. It is paramount that this bridge be restored, with attention paid to bringing back the original appearance of the bridge. As a significant and impressive example of this structure type, it should be receive more attention than it currently has been.
