For Anna University and IIT Madras, the stop to ask for is Eng. College, the name MTC route data uses for the Anna University stop on Sardar Patel Road. Five routes in this guide call there, led by 21G (Broadway to Tambaram) and 23C (Ayanavaram to Besant Nagar). IIT Madras sits on the same road, roughly midway between Raj Bhavan and the Adyar bus terminus, with the CLRI campus opposite, according to an IIT Madras directions page.
Guindy is also a rail and metro hub. The Guindy railway stop (Guindy R.S. in the data), the Concorde stop near Raj Bhavan and the CIPET stop near the industrial estate are all served by different routes, so the right bus depends on which campus you want.
The Guindy stops and who uses them
Eng. College serves Anna University and is the closest named stop to the IIT main gate. Concorde is near Raj Bhavan at the Sardar Patel Road junction. Guindy R.S. is by the suburban station and the race course. CIPET is the stop by the plastics institute of that name near the Guindy industrial estate, and Guindy TVK Estate is the terminus for route 45G.

The gaps quoted here are averages from MTC route data published on our route pages; they may be dated and real waits vary by time of day, so check live timings on the official MTC site or the Chennai One app before you set out.

For Anna University and IIT Madras
From the north and the Marina side, 21G runs through Mandaveli and Kotturpuram to Eng. College, then on to Concorde and Guindy station. From Egmore and Anna Salai, 23C reaches Concorde and Eng. College via Saidapet. From T. Nagar and Kilpauk, 47A does the same. The IIT directions page also names 23C and 47A among buses from Saidapet, though that page was written for a 2013 event, so treat it as a guide to the corridor rather than a timetable.

21G, M70N and 568C stop at Guindy R.S. M152N has a stop at the race course office. CMRL lists a Guindy metro station on its network, which helps if you are coming from the airport or Anna Salai (CMRL).
