[1] In 1799 the ditch was filled up and the current outline of the road built.

Until the 1870s, the Circular Road was considered the de facto eastern boundary of the City of Calcutta as the suburbs to its east, i.e. Manicktala, Rajabazar, Narikeldanga, Ultadanga, and Beliaghata were still semi-urban semi-rural villages.

Named after the renowned chemist Acharya Prafulla Chandra Roy and the renowned physicist and botanist Acharya Jagadish Chandra Bose.
