Trivandrum Capital Region

The Thiruvananthapuram Capital Region or TCR is the area proposed by TRIDA (Thiruvananthapuram Development Authority) by joining adjacent municipalities of Attingal, Varkala, Neyyattinkara and Nedumangad with Thiruvananthapuram city. This was proposed for planning the development of the capital region of Kerala more effectively. The TCR covers most part of the Thiruvananthapuram UA and eyes to develop the surrounding municipalities as satellite towns to the main city.
