Chittoor Thatchur Expressway Route Map, Latest News, Construction Update & Status (2026)

The expressway starts at Keenatampalli near Chittoor and ends at Thatchur near Ponneri, connecting Chittoor district (Andhra Pradesh) with Tiruvallur district (Tamil Nadu) and intersecting with the Bangalore–Chennai Expressway and Chennai Peripheral Ring Road.

Major sections of the expressway are currently opened for trial/public traffic, while the remaining stretch between Uthukottai and Thatchur is under construction.

The entire expressway is targeted for 2026 (subject to NHAI construction schedule), with segments opening in phases depending on construction progress.

Yes, the Chittoor Thatchur Expressway is developed as part of the Bharatmala Pariyojana Phase-I program to strengthen port-bound logistic connectivity.

The expressway passes through Chittoor district in Andhra Pradesh and Tiruvallur district in Tamil Nadu.

Major sections of the expressway are currently opened for trial/public traffic, while the remaining stretch between Uthukottai and Thatchur is under construction.

Land acquisition has been substantially completed across most packages.

The Chittoor Thatchur Expressway is a 116 km, six-lane, access-controlled greenfield highway developed as NH-716B between Chittoor in Andhra Pradesh and the Thatchur/Chennai-side corridor in Tamil Nadu. The project was developed by NHAI under the Bharatmala Pariyojana programme to provide a faster connection between the Chittoor region and the Chennai metropolitan and port-side network.

The Chittoor Thatchur Expressway project involves construction of a six-lane greenfield NH-716B corridor from Chittoor to the Chennai-side network near Thatchur. The 116.1 km NHAI corridor was divided into four construction packages and developed under the Hybrid Annuity Mode (HAM).

The Chittoor Thatchur Expressway route begins near Chittoor in Andhra Pradesh and runs southeast through Chittoor district before entering Tiruvallur district in Tamil Nadu. The corridor passes through the Nagari and Uthukottai region and continues toward the Thatchur-side Chennai highway network. Important access locations include Anupalle, Arthala, Narasimhapuram, Pallipattu, Nagari, Uthukottai, Kumararajapet, S.R. Puram, Veerakaverirajapuram and Pondavakkam.

The Chittoor Thatchur Expressway map shows the approximately 116 km greenfield NH-716B corridor connecting Chittoor with the Thatchur-side Chennai region across Andhra Pradesh and Tamil Nadu. The alignment provides multiple interchanges and access points to connect nearby towns and major roads while keeping through traffic on an access-controlled corridor.

The NHAI project starts at km 0.000 near Varadharajula in the Chittoor region of Andhra Pradesh and extends to km 116.100 near Kannigaipair in Tiruvallur district, Tamil Nadu. The project is commonly called the Chittoor Thatchur Expressway because its wider connectivity leads toward the Thatchur and Chennai-side road network.

The Chittoor Thatchur Expressway follows a new greenfield alignment rather than simply widening the existing highway. The 116.1 km corridor crosses Chittoor district in Andhra Pradesh and Tiruvallur district in Tamil Nadu, with the alignment incorporating interchanges, vehicular underpasses, light vehicular underpasses, bridges, railway overbridges and culverts for local connectivity and uninterrupted through traffic.

The NHAI Chittoor Thatchur greenfield highway has a project length of 116.1 km, commonly rounded to 116 km. The four packages cover km 0.000–43.800, km 43.800–61.380, km 61.380–96.040 and km 96.040–116.100.

The latest official NHAI/Ministry of Road Transport and Highways announcement gives the developed 116 km Chittoor–Thatchur corridor a project cost of ₹5,486.32 crore. Earlier package-level and environmental documents contain different estimates because they were prepared at different stages and for individual packages, so the ₹5,486.32 crore figure is the appropriate current project-level figure.

NHAI implemented the Chittoor Thatchur Expressway through four separate HAM packages. Different concessionaires were appointed for the individual packages, including KNR Ramagiri Infra for Package III and Chittoor Thatchur Highway Private Limited associated with IRB Infrastructure Developers for Package IV. Therefore, the entire 116 km corridor should not be attributed to a single contractor.

The Chittoor Thatchur Expressway has reached the traffic-opening stage. NHAI opened the 116 km six-lane NH-716B corridor to traffic on a trial-run basis on 24 April 2026. This means the main greenfield corridor has been substantially completed, although operational arrangements and remaining associated works can continue to be handled separately.

Yes. NHAI opened the Chittoor–Thatchur NH-716B corridor for traffic on a trial-run basis in April 2026. The official NHAI announcement described the corridor as a 116 km six-lane access-controlled greenfield highway. The trial opening should not be confused with a separate formal inauguration or with completion of every associated facility.

The major latest development is the April 2026 trial opening of the 116 km Chittoor–Thatchur NH-716B corridor. NHAI reported that the corridor had been developed at a cost of ₹5,486.32 crore and includes 24 major bridges, 17 minor bridges, 195 box culverts, 16 vehicular underpasses, 39 light vehicular underpasses, seven interchanges and four road overbridges. NHAI has subsequently continued operational activities on the corridor, including arrangements for user-fee collection and wayside amenities.

The Chittoor Thatchur Expressway passes through Andhra Pradesh and Tamil Nadu. The corridor begins in the Chittoor region of Andhra Pradesh and continues through Tiruvallur district in Tamil Nadu toward the Chennai-side Thatchur network.

The corridor provides access to several locations including Anupalle, Arthala, Narasimhapuram, Pallipattu, Nagari, Uthukottai, Kumararajapet, S.R. Puram, Veerakaverirajapuram and Pondavakkam. These access points allow the access-controlled highway to serve regional traffic while keeping long-distance traffic separated from local roads.

The Chittoor Thatchur Expressway creates a high-capacity access-controlled route from the Chittoor region toward the Chennai metropolitan area and its highway and port network. It is designed to reduce dependence on congested existing roads, improve freight movement and provide faster connectivity for traffic travelling between Andhra Pradesh, northern Tamil Nadu and Chennai.

The 116 km NH-716B corridor is six lanes wide and access-controlled. The project includes 24 major bridges, 17 minor bridges, 195 box culverts, 16 vehicular underpasses, 39 light vehicular underpasses, seven interchanges, four road overbridges and 112 utility crossings. These structures support uninterrupted highway movement while maintaining connectivity across the greenfield alignment.

The Chittoor Thatchur Expressway connects with the wider Bengaluru–Chennai road network at the Chittoor end and provides access toward Chennai through the Thatchur-side network. Its integration with the Bengaluru–Chennai Expressway improves the potential for high-speed travel between Bengaluru, Chittoor and Chennai without routing all traffic through the older urban highway corridors.
