This bridge was a rare example of a riveted continuous through truss. It was particularly uncommon because it had four main spans, but they were configured as two two-span continuous truss bridge components. As a result, if the placement of piers is ignored, the bridge looks like it has two spans, instead of four. In 1991, the bridge was turned into a one-way couplet with the construction of a modern truss bridge next to it. The two bridges made a good comparison since the modern bridge lacks the beauty of the historic bridge with its simple beams that lack riveted elements like v-lacing and lattice.
Missouri once had one of the largest collection of large-span riveted continuous and cantilever truss bridges in the country, not surprising given the Missouri River runs right through the state, and one side of the state is bordered by the Mississippi. Nationwide large historic truss bridges of these types are not common yet are facing a staggering rate of demolition alongside an equally staggering lack of preservation. This is particularly true in Missouri, where preservation of bridges of this size is essentially non-existent with a couple exceptions in the City of St. Louis. The Missouri River has in particular been decimated, and the Daniel Boone Bridge will be one of the last remaining bridges of its kind on the Missouri River when it is demolished.
An excellent opportunity to preserve the Daniel Boone Bridge was dismissed. The Daniel Boone Bridge, which up until demolition serves full Interstate Highway traffic, could certainly have been left standing next to its replacement and been used for non-motorized traffic which cannot use the Interstate Highway itself. Even without rehabilitation, a bridge capable of carrying Interstate traffic could likely carry pedestrians for decades.
