This bridge is composed of two spans from two different eras of construction. The southwestern truss span is a pin-connected Pratt truss of 72.5 feet in length. The northeastern span is a 65 foot rivet-connected Warren pony truss. Commonly, when two different spans are found like this, usually the pin-connected span is the older and original span, and the rivet-connected span would be newer, having been installed when for some reason the original span failed. The Historic Bridge Inventory does not comment or speculate on this possibility for this bridge. Stylistically, the Warren pony truss appears to be an early example of its type, while the Pratt truss appears to be a late example of its type. The 1910 date would be plausible even for the presumed newer Warren truss span. Thus there is a possibility that both spans were erected at the same time, however this would be unusual to see such variances in construction design used at the same time.
The Pratt truss stands out for having very tall trusses for a pony truss. Longer truss spans result in taller truss spans, but this bridge the ratio of length to height appears to favor a taller than normal truss. The Warren pony truss span is noteworthy for its complete lack of vertical members, which is rare among Warren truss bridges. With no verticals in the way, the floor beams rest directly on top of the bottom chord connection gusset plates.
In 1977, the Warren truss span had supplemental bents added under the bridge to bear the load of traffic.
