Short Significance Description:
Part of Motor Road System that is nationally significant under Criterion A for conservation, recreation and transportation, Criterion B for association with John D. Rockefeller, Jr., and Criterion C for architecture & engineering.
Long Significance Description:
The ACAD Motor Road System is significant under Criterion A for illustrating the NPS system-wide goal of providing public access to national parks while conserving natural beauty, Criterion B as an example of John D. Rockefeller, Jr.’s interest in the construction and beautification of roads in the national parks and his collaboration with the NPS, and Criterion C as including excellent examples of the NPS Rustic Design style. The period of significance for the road system begins in 1922 when Superintendent George B. Dorr submitted a plan to the NPS for the park’s first motor road, and ends in 1958 when the final segment of the system was completed.

Construction of the ACAD Motor Road System was conceived to allow the construction of roads for automobiles in the park while preserving its natural beauty. The system began in 1922 when Superintendent Dorr submitted a plan to NPS Director Stephen Mather for a motor road that ran from Eagle Lake Road and along Eagle Lake and Jordan Pond. Rockefeller contributed much of the vistion, resources, and supervision necessary to accomplish the construction of the Motor Road System, his interest stemming from preventing automobile use of the carriage roads that he was constructing on the island. In 1927 the park developed a Master Plan in which all projects that would be characterized by the emerging NPS Rustic Design style, which created a rugged and frontier-like quality appropriate to a wilderness setting while allowing features to be customized with local materials to fit the setting.

Culverts conveyed water from one side of the road to another. Many of the older segments of the historic motor road featured beautifully constructed, dry-laid stone box culverts; concrete box culverts, corrugated metal pipes, and reinforced concrete pipes were also constructed during the historic period, the latter being by far the most common. Many culverts featured inlets constructed with local stone set around the pipe as part of a headwall structure; where the road corrdor was narrow, more elaborate drop-in stone inlets were installed. In 1938 the BPR introduced brick or concrete boxes. In highly visible locations, the BPR continued to use stone headwalls so as to not compromise the rustic character of the roads.
