Koyambedu Junction (Tamil: கோயம்பேடு சந்திப்பு) or otherwise called the Koyambedu Roundtana is an important road junction in Chennai, state of Tamil Nadu, India. It is located north of the Chennai Mofussil Bus Terminus at the junction of the Inner Ring Road and the Poonamallee High Road (NH4) in the Koyambedu area/ locality. The junction is a part of the Golden Quadrilateral project taken up under the National Highways Development Project.
An elevated Parclo interchange is currently under construction by the National Highways Authority of India to decongest the junction which is heavily utilised by interstate buses. This design of parclo grade separator has three arms of the cloverleaf interchange. The construction of the flyover was delayed due to problems in acquiring land that was owned by Tamil Nadu MLA Vijayakanth.
Koyambedu Junction intersects two major roads Ponamallee High Road(NH 4) and 100 Feet Road (Inner Ring Road or Jawaharlal Nehru Road).
