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.

Medians were an important part of the effort to isolate and screen parking areas from the motor roads and to direct traffic flow at intersections. Smaller medians were areas of grass bounded by curbing, while larger medians, more natural-looking, had no curbing and featured grass interspersed with trees and shrubs. In the 1950s mortared rubble medians were installed at larger/busier pullouts to accentuate the separation between the road and the pullout.

Curbing, mostly of local, rough-cut granite, was used in association with parking areas, pullouts, walkways, and medians. After WWII a granite curb with sloped face was introduced, and by the 1950s concrete curbs were also in use. In the 1980s, saw-top granite curbing replaced some sections of the historic concrete curbing.
