Tamil Nadu

The National Highways Authority of India plans to widen the Kamalapuram–Oddanchatram section of NH-83 in Tamil Nadu to four lanes, covering a distance of 36.505 km.

The scheme falls under the first phase of the Bharatmala Pariyojana programme and is funded through a public-private payment model known as hybrid annuity, with a projected spend of Rs 13.19 bn.

This segment sits within the larger NH-83 route that runs from Coimbatore toward Nagapattinam Port on the state's eastern coast, so widening it should tighten links along that whole corridor.

Towns expected to gain better road access include Coimbatore, Tiruppur, Pollachi, Udumalpet and Dindigul, all areas with notable factory and farm output.

Oddanchatram, known for its produce markets, along with pilgrimage town Palani and hill station Kodaikanal, are also named as places that should see improved approach roads once work finishes.

Faster, wider roads could make it easier for manufacturers and farmers in Coimbatore, Tiruppur and nearby areas to move goods to markets and toward port facilities at Nagapattinam.

Smoother travel could also benefit tourism-linked businesses around Palani and Kodaikanal, which depend on visitor traffic, while cutting travel time for local commuters along the route.
