History
In 1873, the intersection — then consisting of Warren, Ridge and Glen Streets — became known as Fountain Square on account of an ornate fountain having been built in front of the Rockwell House. This fountain was removed, however, in 1898 to make room for brick street paving and a trolleyTram

much of the city's commerce had vacated downtown in the latter part of the 20th century.

was contracted by the city to prepare final design plans of the roundabout. The city mayor noted that there were no banks at Bank Square and that it seemed contradictory to refer to a roundabout intersection as a square. As a result, the name Centennial Circle was chosen from among submissions to a name-the-roundabout contest, the name having been submitted by Diane and Jon Swanson of Queensbury.
The roundabout opened to traffic on May 6, 2007. According to a 2008 study, the traffic volume of Centennial Circle has increased twenty percent compared to the intersection it replaced, while at the same time providing drivers with reduced wait times.
