Chennai Bangalore Expressway: Route, Map, Toll Rates and More

The Bangalore Chennai Expressway is changing connectivity between two of South India's major cities. Bengaluru has long been connected to Chennai via highways, but this world-class greenfield project, conceived under the Bharatmala Pariyojana program, is going to transform travel, reducing journey times, enhancing trade and regional economic development. In this blog we discuss the expressway route, expressway map, toll rates and other important details of the project.

Overview

The Chennai Bangalore Expressway is a significant infrastructure project aimed at connecting Chennai to Bangalore through a state-of-the-art 258 km four-lane corridor that is being executed by the National Highways Authority of India (NHAI). It spans the states of Andhra Pradesh, Tamil Nadu, and Karnataka, thus being one of the most monumental expressway schemes not only in India but also in the region. 

The project started in the 1990s and gained renewed momentum in 2018. In January 2021 it was formally designated National Expressway 7 (NE-7). The expressway is expected to cost ₹ 18,000 crore and will reduce travel time to about 2.15 hours (from 5 – 6 hours), which will undoubtedly save precious time for commuters and freight.
