The bus terminus originally functioned at the Broadway terminus near Madras High Court in George Town, in an area covering about 1.5 acres. With the growing population and transportation demand, a new terminus was planned at Koyambedu.

The terminus has 6 platforms in 3 bus fingers with 180 bus bays. It also has an idle parking area for 60 buses and can station 270 buses at any given time. Being the most important entry-exit point of the city, the terminus has a capacity to handle over 2,000 buses and 200,000 passengers a day. The terminus currently handles more than 500 buses at a time, and 3,000 buses and 250,000 passengers a day. The 36.5-acre (148,000 m2) bus terminus has an 17,840 sq ft (1,657 m2) waiting facility for passengers, a 25,000 sq ft (2,300 m2) parking space for auto rickshaws, cabs and private cars, and 16,000 sq ft (1,500 m2) parking space for two-wheelers.

The amenities provided in the terminus include 3 hotels and 3 smaller eateries inside the terminus, 3 locker rooms, 10 travel agency offices, shops, supermarkets, ATMs, dorm rooms (A/C and non-A/C) for rent, toilets, round-the-clock security, pure drinking water free of cost facilitated by a reverse-osmosis treatment plant, a 24-hour Emergency Medical Care Centre, a 24- hour Pharmacy and Free Wi-Fi internet.

It has been estimated that over 500,000 footfalls per day is being recorded at CMBT and over 4,800 buses, including intra-city and mofussil buses, ply in and out of CMBT.

There are provisions for parking 1,500 to 2,000 two-wheelers and 60 cars on the premises of the bus terminus. A two-level underground two-wheeler parking lot was mooted in 2008 to decongest the entrance for the buses, which jostle for space with two-wheelers and cars. Initially, the project cost was estimated at ₹ 90 million. The underground parking project was taken up based on a study that estimated that the number of motorcycles parked there would be increased to 3,000 a day in the future. Work on the 6,000-sq.m project began in January 2009 and was completed in August 2010 at a cost of ₹ 170 million.
