Route 117 was one of the original Rhode Island State highways, instated in 1922. Its alignment has changed little since that time.

In the late 1990s, Route 117's eastern terminus was cut back. Originally, Route 117 stayed with Broad Street through Cranston and into Providence, ending at U.S. 1. The reason the eastern terminus was trimmed back is unclear.
