The Kolkata bus routes that most commuters rely on are the long north-south and east-west corridors that connect Howrah, Esplanade, Salt Lake Sector V, Garia, Behala and the airport. The simplest way to plan any trip is to pick your nearest big interchange (Howrah, Esplanade, Sealdah, Shyambazar, Garia or Karunamoyee), find a bus that runs along your corridor, and confirm the route number and last-bus time on the day of travel. Government buses run by the West Bengal Transport Corporation (WBTC), private buses, minibuses and AC services all share the same roads, and fares are low, usually from around Rs 10 for a short ride and rising with distance. Route numbers and timings change from time to time, so treat this Kolkata bus routes guide as a planning framework and confirm details with the conductor, the official transport department or the Yatri Sathi app before you rely on a specific service.
Metro is faster on the lines it covers, but buses still reach places the metro does not. For the rail side of the picture, read our complete guide to getting around Kolkata.
How Kolkata Bus Routes Work
Kolkata buses are identified by a number or a letter-number code (for example AC12, S-series or a plain number such as 217), and each route is a fixed corridor with a published list of stops. Government (WBTC) buses and private buses often share the same corridor but may carry different numbers. Many routes terminate at the same handful of hubs, which is why learning the hubs is more useful than memorising numbers.
Main Bus Hubs to Know
Howrah Station and Babughat anchor the west. Esplanade (Dharmatala) is the central hub from which buses fan out to the north, south and east. Sealdah, Shyambazar and Ultadanga cover the north and north-east. Garia, Jadavpur and Tollygunge serve the south, while Behala Chowrasta and Joka serve the south-west.
Common Commutes and the Corridors That Serve Them
Howrah to Esplanade and Central Kolkata
This is the busiest short corridor in the city. Buses cross the Howrah Bridge or the Vidyasagar Setu depending on the route, and the ride into Esplanade or B.B.D. Bag usually takes 20 to 40 minutes outside peak hours and much longer in the evening rush. If you are travelling between the two major rail stations, compare options in our Howrah to Sealdah transport comparison.
Salt Lake, New Town and Sector V to the City Centre
The AC 12 service run by WBTC links Shapoorji (New Town) with Howrah through Sector V, Nicco Park, Chingrighata, Science City, Esplanade and B.B.D. Bag. Published listings put the distance at about 27 km, with fares ranging from roughly Rs 10 to Rs 45 depending on where you board, and a bus about every 15 minutes during the day, with first and last buses at roughly 7:30 AM to 8:00 AM and 7:30 PM. Because schedules get revised, confirm the latest timings before you plan a late return.
South Kolkata: Garia, Jadavpur, Tollygunge and Behala
South Kolkata has dense bus coverage toward Esplanade and Howrah, though the Blue Line metro now takes much of the Garia and Tollygunge traffic. Behala and Joka commuters should also look at the Purple Line, covered in our Purple Line guide. Buses remain the better option for the lanes between metro stations.
To and From the Airport
Airport connections run from the VIP Road corridor through Baguiati, Ultadanga and Esplanade. AC shuttle services have been added for the airport and Sector V routes under the Yatri Sathi network, which we covered in our report on the Yatri Sathi AC shuttle expansion. For the rail alternative, see the Airport Metro (Yellow Line) guide.
Bus Fares in Kolkata
Fares are distance-based. Ordinary buses start at a few rupees to roughly Rs 10 for the first stage, and AC buses cost noticeably more, with long AC routes reaching about Rs 45 or above. Exact prices differ by operator and are revised from time to time, so carry small change and ask the conductor for the fare when you board. Do not rely on any single fare figure quoted online without checking.
How to Find the Right Bus
Three methods work well. First, use the Yatri Sathi app, which the state transport department promotes for government buses and AC shuttles. Second, ask the conductor or a nearby shopkeeper for the route number toward your destination, because the number painted on the windscreen is more reliable than a remembered one. Third, check the official West Bengal Transport Department website for announcements on new or changed services.
Tips for Riding Kolkata Buses
Board at designated stops where possible, since buses may not wait long. Keep valuables in front of you during rush hour and avoid the 8:30 AM to 11 AM and 5 PM to 8 PM peaks if you can. Women can use the seats reserved for them near the front. In monsoon, allow extra time because waterlogged stretches slow the buses, and in Durga Puja week expect diversions around pandal areas. Combining a bus with the metro is often the fastest option, and the official Kolkata Metro Railway website lists current timings.
