Why Route 70V matters
The only direct MTC bus from CMBT to the deep south GST Road corridor: Vandalur Zoo, Urapakkam, and Guduvanchery. It provides a unique connection between the city’s western bus hub, the KK Nagar belt, the airport area, Tambaram, and the Vandalur Zoo destination — all in a single ride
Key Stops with Landmarks
Route 70V is a long GST Road route with several notable destinations. Key stops are described below — for intermediate stops (Irumbuliyur, Perungulathur, etc.) it is a through-service for residential commuters in the deep south GST Road belt.

Who Uses Route 70V
CMBT and K.K. Nagar Residents to Airport
CMBT-area residents and K.K. Nagar residents use Route 70V as a budget airport connection. The low frequency (~2 hours) limits its use for tight flight schedules, but it is the cheapest way from CMBT to the airport.
Zoo Visitors from Western Chennai
Families from CMBT, K.K. Nagar, and the Vadapalani belt use Route 70V on weekends for day trips to Vandalur Zoo — one of the few direct CMBT-to-Zoo MTC bus connections.
Deep South GST Road Commuters
Residents of Irumbuliyur, Perungulathur, Urapakkam, and Guduvanchery depend on Route 70V for CMBT connections — particularly those who travel interstate or need to reach K.K. Nagar without changing at Tambaram.
Traveller Tips
Route 70V runs every 2 hours — very low frequency. Check the schedule before leaving for a bus stop.
For airport travel from CMBT, Route 70V works if you have a time buffer. The Metro from Koyambedu to Airport is faster and runs frequently — prefer the Metro for airport travel.
For Vandalur Zoo, Route 70V is one of the direct CMBT options. Verify bus timing aligns with zoo opening hours (9 AM to 5:30 PM, closed Tuesdays).
At Tambaram, you can board Route 70V mid-route if you miss the CMBT departure — the bus also stops at Tambaram bus stand.
