Chennai to Bangalore by Taxi — Complete Route Guide (2026)

The Chennai to Bangalore corridor is one of India's busiest intercity routes, with thousands of vehicles making the 346 km journey daily. Whether you are heading for a business meeting in Whitefield, visiting family in Jayanagar, or catching a connecting flight at Kempegowda International Airport, this comprehensive guide covers everything you need to know — route options, toll costs, the best food stops, fuel stations, and how to book the most comfortable ride. We have driven this route hundreds of times and distilled all of that experience into one practical, up-to-date resource.

Route Overview

Before diving into the details, here is a quick snapshot of what the Chennai-Bangalore journey looks like:

• Distance: 346 km (via NH48, the recommended route)
• Duration: 5.5–6.5 hours depending on traffic and route choice
• Total Tolls: Approximately Rs.450 for a sedan/hatchback
• Two Main Routes: NH48 (via Vellore & Krishnagiri) and NH46 (via Ranipet & Ambur)

Both routes converge near Krishnagiri before entering Karnataka through Hosur. The route you choose depends on your priorities — speed versus scenery, tolls versus road quality. Let's break it down.

NH48 vs NH46 — Which Route Should You Take?

This is the first decision every traveller faces. Here is a side-by-side comparison to make the choice easy:

Our recommendation: NH48 is the clear winner for most travellers. The road quality is significantly better, the journey is faster by at least 30–60 minutes, and the driving experience is far less stressful thanks to the well-maintained 4-lane expressway. Choose NH46 only if you specifically want to explore Ambur (famous for its legendary biriyani) or want to save approximately Rs.100 on tolls.

Detailed Stop-by-Stop Guide (NH48)

Here is a kilometre-by-kilometre breakdown of the NH48 route, so you know exactly what to expect at every stage of the journey.

Km 0–50: Chennai to Sriperumbudur

Getting out of Chennai is the trickiest part of the entire trip. The Poonamallee bottleneck and the stretch leading to Sriperumbudur can eat up 45–60 minutes during peak hours. Our strongest advice: leave before 6 AM to glide through this section in under 30 minutes. As you pass through, you will see the massive Samsung and Hyundai manufacturing plants on either side of the highway — a reminder that this corridor is one of South India's industrial lifelines. The first toll plaza appears around km 30. Keep your FASTag active to breeze through without stopping.

Km 50–136: Sriperumbudur to Vellore

Once past Sriperumbudur, the highway opens up into a smooth 4-lane stretch and the driving becomes genuinely pleasant. You will pass the Kanchipuram turnoff around km 70 — if you are a temple enthusiast, this ancient city is worth a separate trip entirely. Vellore appears at the 136 km mark, approximately 2 hours into the journey, and makes an excellent first rest stop. The CMC (Christian Medical College) hospital is a prominent landmark here. This is where many drivers and passengers choose to take a quick 15-minute chai break before pushing on to the midpoint.

Km 136–230: Vellore to Krishnagiri

The terrain begins to change as you leave Vellore. You will notice a gradual elevation gain and the landscape transforms into beautiful rocky formations dotted with scrub vegetation. The drive is scenic and the road remains excellent. Krishnagiri appears at the 230 km mark, roughly 3.5 hours from Chennai, and serves as the natural midpoint of the journey. This is your must-stop for food — the town has several excellent restaurants and the break will keep your driver fresh and alert for the second half.

Km 230–310: Krishnagiri to Hosur

Many regular travellers consider this the best stretch of the entire highway. The road is smooth, well-maintained, and the traffic is generally lighter than the Chennai or Bangalore ends. Hosur is essentially the gateway to Bangalore — the Tamil Nadu-Karnataka border crossing happens here. You will notice a distinct change in road signage and the kilometre markers switch to Karnataka state format. The toll plazas in this section are well-managed and FASTag lanes move quickly.

Km 310–346: Hosur to Bangalore

This is where patience becomes essential. The final 36 km from Hosur into Bangalore city can take anywhere from 30 minutes to over an hour depending on the time of day. The Electronic City stretch and the infamous Silk Board junction are notorious bottlenecks that can add 30–60 minutes during peak hours (8–10 AM and 5–8 PM). Pro tip: If you are heading to North or West Bangalore (Rajajinagar, Malleshwaram, Yeshwanthpur), ask your driver to take the NICE Road toll route to bypass Silk Board entirely. The Rs.200 toll is well worth the 45 minutes you will save sitting in traffic.

Best Food Stops Along the Way

Food is a serious part of any South Indian road trip. Here are the tried-and-tested restaurants our drivers and passengers recommend:

1. A2B (Adyar Ananda Bhavan), Vellore (~2 hour mark) — Reliable South Indian meals, clean restrooms, and quick service. The mini tiffin combo is perfect for a short stop.
2. Hotel Saravana Bhavan, Krishnagiri (~3.5 hours) — The classic Tamil Nadu thali experience with fast service and consistent quality. A favourite among long-distance drivers.
3. Sri Annapoorna, Krishnagiri — Another solid vegetarian option with excellent filter coffee. Slightly less crowded than Saravana Bhavan on weekends.
4. Kamat Upachar, Hosur — Karnataka-style meals with both veg and non-veg options. The ragi mudde and chicken curry are popular choices here.
5. Ambur Star Biriyani (NH46 detour) — For biriyani lovers, this legendary restaurant in Ambur is worth the 30-minute detour via NH46. The Ambur-style biriyani is unlike anything you will find elsewhere in Tamil Nadu.

Toll Breakdown (NH48)

Tolls are one of the most frequently asked-about costs on this route. Here is the complete breakdown for 2026:

FASTag is strongly recommended. Cash lanes at toll plazas often have long queues, especially on weekends and holidays. If your taxi does not have a FASTag, keep Rs.500 in small denominations ready to avoid delays.

Fuel Stations & Emergency Information

NH48 is a major national highway, so fuel availability is never a concern. Indian Oil, Bharat Petroleum, and Hindustan Petroleum stations appear every 30–40 km along the route. That said, we recommend starting with a full tank and topping up at Krishnagiri (the midpoint) for complete peace of mind, especially if you are driving an SUV with higher fuel consumption. In case of any roadside emergency, keep these numbers handy:

• National Highway Helpline: 1033
• Police: 100
• Ambulance: 108
• Bharat One Way Taxi 24/7 Helpline: +91 93420 46010

Taxi Fare Breakdown — Chennai to Bangalore

One-way taxi fares from Chennai to Bangalore vary by vehicle type. Here are the current rates from Bharat One Way Taxi (as of March 2026):

All fares include driver bata (Rs.300). Tolls and parking charges are extra and paid directly at the toll plaza. There are no return fare charges — you pay only for the one-way distance, which saves you up to 40% compared to booking a round-trip cab from a local operator.

Pro Tips for the Chennai–Bangalore Drive

• Leave Chennai by 5:30 AM for the smoothest possible run. You will clear Sriperumbudur before the morning traffic builds and reach Bangalore well before the evening rush.
• Avoid Friday evenings (heavy Bangalore-to-Chennai weekend traffic) and Sunday evenings (the reverse flow). Saturday mornings are usually the quietest.
• Festival seasons (Diwali, Pongal, Dasara) can double your travel time. Book your taxi at least 3–5 days in advance during these periods, as demand spikes dramatically.
• Book one-way taxi to save 40% compared to round-trip fares. With Bharat One Way Taxi, you pay only for the distance you travel — no empty return charges.
• Keep Rs.500 cash as backup for tolls, in case of FASTag issues or toll plazas that have technical problems with electronic payment.
• Carry a light jacket — the AC can get cold during a 6-hour drive, and the temperature drops noticeably once you gain elevation past Vellore.
