The route connects four of India's most populous cities - Mumbai , Pune , Bangalore and Chennai and has a length of 1,235 km. It runs through the states of Maharashtra , Karnataka , Andhra Pradesh and Tamil Nadu .
NH 4 forms around 90% of the Mumbai – Chennai section of the Golden Quadrilateral , a motorway project connecting the cities of New Delhi , Chennai, Mumbai and Kolkata . As part of this project, the NH 4 was expanded from a single lane with two lanes to a two-lane street with four lanes. Within the state of Karnataka, the route is also known as the Pune-Bangalore Road. The Mumbai-Pune section was supplemented by the Mumbai Pune Expressway in 2002 .
The highway runs through Satara , Karad , Kolhapur , Belgaum , Dharwad , Hubli , Davangere and Tumkur in Maharashtra and Karnataka . Between Bangalore and Chennai, the trunk road is supplemented by the national highways NH7 and NH46 .
The Pune bypass is a six-lane road with two-lane residential streets that run parallel to the main carriageways on both sides. The city of Katraj is crossed by a tunnel.
NH4 passes the towns of Sangli and Miraj around 40 km away .
Reorganization of the National Highway numbering
In May 2010 the Indian government adopted a new system for numbering national highways . The nationwide implementation of the new system, which is supposed to lead to easier orientation, has been delayed, however. (As of November 2011)
