This bridge is an unusual multi-span continuous reinforced concrete slab. The slab has a variable depth (arched) design, which has the side effect of giving an otherwise visually unappealing structure type some aesthetic quality. Original railings remain on the bridge.

Discussion of Bridge
The 1949 rigid frame bridge is historically and technologically significant as a complete example of a continuous rigid frame bridge. It is the longer and more complete of the two examples built by the MSHC in the late 1940s. It represents important advances in engineering knowledge and strength of materials in the postwar period. Rigid frame bridges for 35' to 85' span lengths became common in Maine during the 1930s, but multiple span application required difficult and sophisticated stress analysis because of the indeterminate nature of rigid frame structures, and they were rarely attempted until the 1940s. The bridge is judged to have high preservation priority because it is the most significant, extant example of its type/design.
