The TVK-led Tamil Nadu government has scrapped the proposed Kancheepuram New Town development project, withdrawing a 2023 notification that had authorised the Chennai Metropolitan Development Authority (CMDA) to prepare a comprehensive urban expansion and heritage revitalisation plan for the historic temple town. The decision, formalised through a Government Order dated 10 August 2026 by the Housing and Urban Development Department, marks a significant reversal of a major planning initiative launched under the previous Dravida Munnetra Kazhagam (DMK) government.

What the Scrapped Plan Entailed

Formally titled the 'New Town Development Plan for Kancheepuram New Town and Detailed Development and Heritage Revitalisation Plan for Kancheepuram Town 2025-2045', the project was conceived to bring order to the city's rapid and largely unregulated growth. In February 2023, the then DMK government notified its intention to develop a new town across 62.78 square kilometres, spanning 18 revenue villages.

The proposal aimed to channel Kancheepuram's expansion toward National Highway 48, while improving transport connectivity, civic infrastructure, and land-use planning. Authorities had flagged haphazard commercial development, worsening traffic congestion, and mounting pressure on public amenities as pressing concerns. The impact of unchecked urbanisation on the town's temples, traditional neighbourhoods, and heritage character was also cited as a key rationale for the specialised revitalisation component. Following the 2023 notification, CMDA had begun preliminary work on both the new-town blueprint and the detailed heritage plan for the 2025-2045 period.

A Pattern of Reversals

The Kancheepuram decision is not an isolated move. It follows the TVK government's earlier abandonment of the proposed Parandur greenfield airport and the cancellation of a ₹205.89 crore work order for the Global Sports City at Semmencheri. Notably, while the airport project was dropped outright, the government indicated that the sports-city proposal would be redesigned over a larger area.

This is the latest in a series of infrastructure and development reversals that critics argue signals a broader shift in the government's urban planning priorities — though the administration has not publicly articulated a replacement strategy for the Kancheepuram project.

Uncertainty Over Tamil Nadu's New-Town Policy

The scrapping of the Kancheepuram plan has cast a shadow over Tamil Nadu's wider new-town development strategy. The Housing and Urban Development Department's 2026-27 policy note, tabled in the state Assembly, makes no reference to development plans previously proposed for Thirumazhisai, Minjur, Tiruvallur, Mamallapuram, Chengalpattu, Maraimalai Nagar, and Sriperumbudur.

The omission, coupled with the Kancheepuram withdrawal, has raised questions among urban planners and civic groups about whether the government intends to review, restructure, or abandon the broader new-town development framework altogether.

What Happens Next

With the CMDA's preparatory work now halted, Kancheepuram's heritage zones and peri-urban areas will revert to existing planning frameworks — which authorities had themselves deemed inadequate to handle the town's growth pressures. The government has not announced an alternative plan for managing Kancheepuram's urban expansion or heritage conservation. Stakeholders, including temple authorities and local civic bodies, are expected to seek clarity on the town's planning future in the coming weeks.
