Kilambakkam Bus Stand, officially known as the Kalaignar Centenary Bus Terminus (KCBT), is a major bus terminus located in the southern suburbs of Chennai, Tamil Nadu. Spread over an area of 88.52 acres (358,200 m²), it is situated along GST Road. It opened to the public on 30 December 2023 and was built to decongest the Chennai Mofussil Bus Terminus (CMBT) at Koyambedu.
Kilambakkam bus terminus is the largest bus station in the world by area, surpassing even major international hubs like Singapore’s Woodlands Bus Interchange in physical footprint (though not in daily passenger volume).

Full Route Map and Major Destinations
Kilambakkam handles bus routes to destinations across Tamil Nadu, Puducherry, and Kerala. Since its opening:
- All southbound buses — including SETC, TNSTC, and Omni buses — were shifted here from CMBT Koyambedu on 30 December 2023
- Major southbound destinations reachable from here include cities across southern Tamil Nadu (Madurai, Trichy, Tirunelveli belt) and onward connections into Kerala and Puducherry
- Westbound buses continue to operate from CMBT in Koyambedu, while northbound buses operate from the Madhavaram bus terminus
Simplified Route Direction Map
Chennai now operates on a three-terminus model by direction:
| Direction | Terminus |
|---|---|
| South (Tamil Nadu south zone, Puducherry, Kerala) | Kilambakkam (KCBT) |
| West | CMBT, Koyambedu |
| North | Madhavaram Bus Terminus |
This split was implemented specifically to decongest Koyambedu and distribute long-distance bus traffic across the city.
Connectivity from Chennai City
- The terminus is connected to other parts of the Chennai Metropolitan Area and suburbs via MTC (Metropolitan Transport Corporation) buses
- Numerous local MTC bus routes (such as 500, 515B, 555G, 91V, 104C, and others) connect Kilambakkam Bus Station to greater Chennai
- The nearest railway connection is Urapakkam Railway Station, roughly a short walk/ride away
- Metro connectivity: Kilambakkam is planned to be connected to the Chennai Metro Blue Line and Purple Line in future phases, which will significantly ease access
- Prepaid autos and taxis are available on-site for last-mile connectivity at fixed government rates
Why Kilambakkam Bus Stand Matters
- It decongests Koyambedu (CMBT), which had become overcrowded relative to the city’s traffic growth
- Its sheer scale — the largest bus station in the world by area — allows for organized, high-capacity operations
- Average weekday footfall runs between 20,000–30,000 passengers, spiking above a lakh (100,000+) during weekends and festival seasons
- It anchors long-term urban development in Chennai’s southern corridor, with rising interest in nearby real estate and commercial development around the terminus
Travel Tips for Passengers
- Check your terminus before traveling — since services are now split by direction (south/west/north), verify Kilambakkam is the correct terminus for your route before heading there.
- Plan extra travel time — it’s located outside the core city on GST Road, so factor in longer approach times compared to the old Koyambedu stand.
- Use prepaid auto/taxi counters rather than negotiating informally, to avoid overcharging.
- Check the CMDA portal — information on government bus operations from Kilambakkam is available on the Chennai Metropolitan Development Authority (CMDA) web portal, in both Tamil and English.
- Arrive early on weekends/holidays, since footfall surges dramatically during these periods.
- Omni bus travelers should double check pickup points, as private Omni bus pickup arrangements changed significantly after the shift from Koyambedu.
