Union Cabinet approves ₹2,157 crore highway expansion in Tamil Nadu
The Union cabinet on Friday approved a 46-kilometre (km) National Highway project in Tamil Nadu between Marakkanam and Puducherry at a cost of Rs 2,157 crore. 'Upon completion, the Marakkanam–Puducherry section will play a pivotal role in regional economic growth, strengthening connectivity between major religious and economic centres, boosting tourism to Puducherry, and opening new avenues for trade and industrial development,' the Cabinet Committee on Economic Affairs said in a statement. The project will be developed in Hybrid Annuity Mode — this involves the authority paying 40 per cent of the cost upfront to the developer, with the remaining being paid in annuities. Currently, connectivity between Chennai, Puducherry, Viluppuram and Nagapattinam is dependent on the existing two-lane National Highway 332A (NH-332A) and associated State Highways, which experience significant congestion due to high traffic volumes, especially in densely populated stretches and key towns along the corridor, the cabinet said. The government expects that the four-laning will decongest the existing corridor, improve safety, and cater to the mobility needs of rapidly growing towns such as Chennai, Puducherry, Viluppuram and Nagapattinam. The upgraded corridor will also enhance multi-modal integration by connecting with two railway stations (Puducherry, Chinnababusamudram), two airports (Chennai, Puducherry), and one minor port (Cuddalore), thereby facilitating faster movement of goods and passengers across the region. The average daily traffic in 2024–25 on the highway was estimated at 17,800 passenger car units. The project will also generate approximately 800,000 person-days of direct and 1 million person-days of indirect employment, and will open new avenues of growth, development and prosperity in surrounding regions, according to the statement.

Centre okays widening of ECR stretch from Marakkanam to Puducherry at Rs 2,157 crore
ECR PUDUCHERRY : The Union govt has approved widening of the East Coast Road (ECR) to a four-lane stretch for 46 km from Marakkanam in Villupuram district of Tamil Nadu to Union territory Puducherry at a cost of Rs 2,157 crore. A release from the Press Information Bureau (PIB) stated that the Cabinet Committee on Economic Affairs, chaired by the Prime Minister, approved the project, which would be developed on a hybrid annuity model (HAM). The release mentioned that currently, the connectivity between Chennai, Puducherry, Viluppuram, and Nagapattinam relies on the existing two-lane National Highway 332A (NH-332A) and associated state highways (SH). (Some stretches of the ECR are already four-lane). These NH and SH experience significant congestion due to high traffic volumes, especially in densely populated stretches and key towns along the corridor. You Can Also Check: Chennai AQI | Weather in Chennai | Bank Holidays in Chennai | Public Holidays in Chennai To address these challenges, the project would upgrade approximately 46 km of NH-332A from Marakkanam to Puducherry to a four-lane configuration. This will decongest the existing corridor, improve safety and cater to the mobility needs of rapidly growing towns such as Puducherry, Viluppuram and Nagapattinam, it said. The project alignment integrates with two major national highways (NH-32, NH-332) and two state highways (SH-136, SH-203), providing seamless connectivity to key economic, social, and logistics nodes across Tamil Nadu. Additionally, the upgraded corridor will enhance multi-modal integration by connecting with two railway stations (Puducherry and Chinnababusamudram), two airports (Chennai and Puducherry), and one minor port (Cuddalore), thereby facilitating faster movement of goods and passengers across the region. The release said upon completion, the Marakkanam-Puducherry section would play a pivotal role in regional economic growth, strengthening connectivity between major religious and economic centres, boosting tourism to Puducherry, and opening new avenues for trade and industrial development. The project would also generate approximately eight lakh person-days of direct and 10 lakh person-days of indirect employment, opening new avenues of growth, development, and prosperity in surrounding regions, it said.
