The National Highways Authority of India (NHAI) has planned to construct 1,000 km of expressways on the BOT (toll; build-operate-transfer) model.

Expressway construction is part of the sixth phase of the National Highways Development Programme. The official said they would need to expand the ambit of the award structure, by adding more incentives for the developer in the concession agreements. NHAI estimates a km of expressway would cost around Rs 55 crore to build. It is discussing models to offer longer concession periods and land pockets for real estate development along the stretches, to attract developers for the project.
