Significance: This bridge is the last remaining Baltimore (Petit) through-truss bridge in the state. The current structure represents three different phases of construction: Phase 1 - the center span was erected in 1902 by the American Bridge Co. to replace the center wooden covered section lost in spring flooding; Phase 2 - the spans at either end of the center span were added in 1911 by the Boston Bridge Works Co. to replace the remaining wooden covered bridge section; and Phase 3 - three pony trusses (no longer extant) were erected at the west end of the existing structure; replaced with a steel girder truss section in 1934 and 1963.
