I found this while working on a buried bridge structure about half a mile away on the same trail. This structure was built in the 1960's when the the trail was built on an old rail bed. The structure has no signs of deterioration inside or out - in spite of being located below an interstate in the northern US and being subjected to deicing salts every winter. All indications are that this structure should be able to easily achieve a 100+ year service life."},"13":{"Tstamp":"1774626947","field-type":"text-f","field-title":"Name","field-content":"joel hahm"}}
