Significance: The French King Bridge is one of four known steel deck arch bridges in Massachusetts identified in the Massachusetts Department of Public Works (MDPW) database, and has the sixth longest span of all the bridges in the state under MDPW purview. It is of engineering interest as an unusual development of the uncommon three-span, "cantilivere arche" bridge type, in that definite reactions were jacked into its steelwork at the conclusion of construction, resulting in a bridge which is structurally continuous across four supports. The bridge was the crucial link in the establishment of a safe and efficient highway, which replaced a very dangerous section of road between Erving and Greenfield in the early 1930s.
