This cache will take you to a small rare keystone bridge that has been preserved by re-routing the road and constructing a new bridge. Most times of the year, the bridge is totally obscured from view due to heavy vegetation growth in the road ditch.
Keystone arch construction requires that carefully shaped stones be laid in place over a temporary wooden support until the last center stone (the “keystone”) completed the arch to lock the structure together allowing the wooden support to be removed.
This is one of several small bridges originally contracted by the county around the turn of the century utilizing the abundant limestone which could be locally quarried. Built in 1899 by Josef Vogt of Guttenberg, it has out-survived other bridges built at the same time of traditional timber or steel stringers. The bridge exhibits an exceptionally high degree of craftsmanship and historical integrity and was added to the National Register of Historical Places in 1998.
Please park safely on the shoulder of the gravel road. (See additional coordinates for recommended parking.)
The cache: The cache is a small lock’n’lock type container with a logbook, pencil, and starts with a few nice trade items. Please sign the log, trade fairly, and return the cache to its original location and state of concealment for others to enjoy.
