The photos above and below are of a 120 foot long pony truss bridge on a major road in Logan County north of Guthrie. Pony trusses over 100 feet in length are very uncommon, as conventional practice of that era was to use through-truss spans for lengths over 100 feet. Several 120 foot through trusses can be found on these pages, and most, if not all of them date to before 1930. However, this bridge I would say, dates to probably between 1931-1934. As stated above, the main span is 120 feet with two approaches measuring about 60 feet each. The bridge is standard OSHC design and looks to be in very good condition. There is no posted weight limit.
