The traffic circle has a long history of keeping traffic moving smoothly here in the United States ever since William Phelps Eno designed the Columbus Circle in New York City that was built in 1905. We are not sure of the location of this circa 1960 photo taken in the City of Providence, Rhode Island, but with the nickname Suicide Circle we are sure a few of our readers can tell us something about it. Let us know what you see that is of interest in the photo. Check the enlargeable images below for more details. The photo is courtesy of the Providence, Rhode Island Archives.
