The islet consists of two hamlets: Mela Ramanallur and Keezha Ramanallur.[1]
A bridge connecting the islet to Alagiyamanavalam was opened to the public in February 2016. Prior to that, coracles were often used to cross the river to the mainland, with floats and bullock carts used during summer;[2] floods would often completely cut off the islet from the mainland.
There remains one connection from the mainland to the islet, . Another bridge, which planned to connect south to Thanjavur district, received of funding from the Tamil Nadu Government and had the foundation stone laid by 2017, but has yet to be completed. A September 2019 incident, in which three people were killed when a boat capsized carrying them back from Mela Ramanallur to Thanjavur district, renewed demands for the bridge to be completed.[3] [4]
