Why Route 37G matters
One of Chennai’s most important cross-city routes, running from the north-east (Vallalar Nagar / Tondiarpet belt) across the entire city through KMC, Sterling Road, Vadapalani, Virugambakkam, and Porur to Iyappanthangal in the west. It is essentially a city spine connecting communities that would otherwise require multiple transfers
All 14 Stops with Landmarks and Local Context
Route 37G is one of Chennai’s definitive cross-city arteries. Starting at Vallalar Nagar in the north (near the Tondiarpet-Wimco industrial belt), it crosses through the city’s educational and medical spine (KMC, Sterling Road) before entering the western residential and commercial belt (Vadapalani, Virugambakkam, Porur) to reach the IT-zone frontier at Iyappanthangal.

Who Uses Route 37G
Cross-city Commuters — North to West Chennai
Route 37G is functionally a city spine. IT professionals working in Porur and Iyappanthangal who live in North Chennai (Tondiarpet, Perambur, Choolai, Purasaiwakkam) use this route to avoid multiple transfers — a journey that would otherwise require going through Broadway and taking a second bus.
Vadapalani Temple Pilgrims from North Chennai
The Vadapalani Murugan Temple draws enormous crowds. Pilgrims from Vallalar Nagar, Tondiarpet, and the North Chennai belt use Route 37G for direct access to Vadapalani, especially on Tuesdays and Fridays.
KMC Hospital Patients
Route 37G is one of the primary links to Kilpauk Medical College Hospital from both North Chennai (Vallalar Nagar) and West Chennai (Porur, Iyappanthangal). Medical patients and their attendants rely heavily on this route.
Students
The corridor serves multiple schools and colleges. KMC medical students, Lady MCTM school students, and engineering college students in the Porur belt all generate significant ridership.
Traveller Tips
Route 37G’s 5-minute frequency makes it one of MTC’s most reliable cross-city routes. It effectively functions as a transit spine for the North-to-West diagonal.
At Vadapalani, you can transfer to the Metro Green Line for faster travel to CMBT, Anna Nagar, or Thirumangalam.
For Porur IT Park employees, Route 37G is the most direct bus from North Chennai. However, during peak hours (7-9 AM and 5-8 PM), the Vadapalani to Porur stretch can be congested — budget extra time.
