The road from Bangalore to Chennai is a long one. This is the reason cab booking makes the most sense. The major route is via the Mumbai highway. To take this route, you first need to take the Langford road till you reach Hosur road. Then you need to take the National Highway 48 till you reach the Poonamallee High road. From there you need to reach the Sydenhams road. You will then reach your destination in no time.
The best time to visit Chennai is between November and February. These are the peak winter months and the temperature is perfect for sightseeing and exploring the Chennai beaches.
There are three routes to reach Chennai from Bangalore. The fastest is via Mumbai Highway. You can also take two alternative routes. One is via National Highway 75 and the Vellore Chennai road. This journey will take you a little over seven hours to complete. The second alternate route is via National Highway 77 and National Highway 32. This journey will take over 8 hours to complete.
The roads between Bangalore and Chennai are excellent. The roads are wide and there are three lanes on either side. You will also find a number of toll booths along the way. So you will need to be ready to pay toll at these booths. However given the condition of the roads, it is worth paying toll because the money is used for maintenance of the highways.
