Union Ports and Shipping Minister Sarbananda Sonowal announced on Wednesday that the Union Cabinet, chaired by Prime Minister Narendra Modi, has approved the construction of a new coastal highway connecting Rameswaram in Tamil Nadu to Paradip in Odisha. The minister said the corridor will span 163.180 km at a total project cost of ₹8,300.79 crore, marking a fresh push for port-led connectivity along India's eastern seaboard.

Context

In his post on X, Sonowal wrote that the 'Cabinet chaired by Hon'ble PM Shri Narendra Modi ji approves the construction of a new coastal highway from Rameshwar to Paradeep'. He tagged the announcement under #CabinetDecisions, situating it within the latest batch of Union government clearances.

The proposed corridor links two strategically significant coastal anchors. Rameswaram is a major pilgrimage town on the Gulf of Mannar, while Paradip is one of India's largest cargo-handling ports on the Bay of Bengal. A direct coastal alignment would knit together stretches of Tamil Nadu, Andhra Pradesh and Odisha that currently rely on inland highways for north-south freight movement.

Policy backdrop

The approval extends a decade-long policy arc aimed at integrating India's ports with its road network. The Sagarmala Programme, launched in 2015, was conceived to drive port-led development and coastal road connectivity. The Bharatmala Pariyojana, cleared in 2017, folded port and coastal corridors into its broader highway framework.

The National Logistics Policy, unveiled in 2022, further emphasised multimodal coastal infrastructure as a lever to bring down logistics costs, which the government has been seeking to reduce as a share of GDP. The new Rameswaram-Paradip alignment is also expected to plug into the PM Gati Shakti national master plan, which maps infrastructure projects across ministries to avoid duplication and bottlenecks.

Stakeholders and impact

Port operators along the eastern coast stand to gain from improved hinterland access, particularly the cluster of ports between Chennai, Visakhapatnam and Paradip. Faster road links between port gates and industrial clusters typically translate into lower turnaround times for cargo and reduced reliance on congested national highways further inland.

Coastal communities, including fisherfolk and small traders, are the other constituency directly affected. While better roads can open up markets and tourism flows, alignment decisions in coastal stretches often trigger questions on land acquisition, livelihood displacement and coastal regulation zone clearances. The logistics sector, which has lobbied for dedicated freight-friendly coastal arteries, is likely to view the project as a structural addition rather than an incremental upgrade.

For the states involved, the highway offers a fresh axis of economic activity. Tamil Nadu and Odisha anchor the two ends, while Andhra Pradesh, with its long coastline, is the natural through-state for any continuous coastal alignment between the two.

What's next

The immediate focus will shift to detailed project reports, environmental and coastal clearances, and land acquisition coordination between the Ministry of Ports, Shipping and Waterways and the concerned state governments. The pace at which these procedural steps are completed will determine when ground-breaking can realistically begin.

For Sonowal, the announcement reinforces the ministry's positioning as a driver of large-ticket maritime infrastructure spending. If executed on schedule, the ₹8,300.79 crore corridor could become a template for similar coastal alignments on the western seaboard, deepening the government's bet that port-anchored highways are central to India's next phase of trade-led growth.
