This bridge is a good example of a one-lane concrete through girder. Likely because of its relatively early 1915 construction date as well as its narrow, one-lane design, the bridge has surprisingly lightweight girders that do not look much more massive than one might expect with non-structural bridge railing found on other bridge types like a concrete t-beam bridge. The bridge has articulated floorbeams that are visible under the deck. The historic integrity of the bridge is very good.

Statement of Significance
From a structural perspective, the designer of this bridge produced rather standard through-girder spans. They are, though, unusually well decorated.
Because of its greater rigidity, the reinforced concrete through girder can be extended beyond the T-beam's ordinary limit of span (40' - 60' long). In a through structure, a pair of girders - large beams that
receive their loads from other beams - flank the roadway and usually carry the deck above floor beams (which run from girder to girder and whose reinforcing rods are interlocked with those of the girders). The through girder is
preferred where the roadway is not far above stream level and T-beams could obstruct the watercourse more than would girders which do some of their carrying above the level of the road.
