A 144-kilometer portion of the Chennai-Tirupati National Highway will be widened, greatly reducing the time required to travel by vehicle from Chennai to Mumbai and Tirupati.

This is part of the Chennai-Surat express highway project, which will decrease the distance between Chennai and Mumbai by at least 120-130 kilometres by passing through Renigunta, Mahabubnagar, Akkalkot, Solapur, and Nashik.

According to official records obtained by TNIE, the Chennai-Tirupati NH 205, which runs from Tiruvallur to the Tamil Nadu-Andhra Pradesh border, is planned to be upgraded from two lanes to four lanes.

Additionally, the four-lane section from the TN-AP border to Tirupati will be upgraded to a six-lane road. The National Highways Authority of India is presently preparing the Detailed Project Report for the upgrade.
