This bridge is an unusual variant of a timber stringer bridge that could perhaps be best classified as a "hollow timber box beam". The bridge superstructure at first glance appears to be a traditional timber stringer, however the structure is actually a hollow "box". It is not known if there is any reinforcing material inside like was sometimes done for concrete arch bridges. The bridge bears some resemblance to the northernmost vehicular bridge over the Mississippi River at the Headwaters - on Wilderness Drive/Park Drive: http://bridgehunter.com/mn/clearwater/bh81882/
