Phase-A: Approved in 2005, it included about 4,099 km length of roads (3,014 km of NH and 1,085 km of State roads). The SARDP-NE Phase ‘A’ is expected to be completed by 2023–24. Phase-B: It covers 3,723 km (2,210 km NHs and 1,513 km of State roads) of road. Phase ‘B’ of SARDP-NE shall be taken up after completion of Phase ‘A’. Bharatmala is a centrally-sponsored and funded road and highways project of the Government of India, started in 2017, with a target of constructing of new highways at an estimated cost of . Bharatmala Phase I plans to construct of highways (including the remaining projects that were under NHDP) by 2021–22, at an estimated cost of . In 2021, Asia's longest high speed track, National Automotive Test Track was inaugurated in Indore, which would be used to measure the maximum speed capabilities of high-end cars and other categories of vehicles. India's rate of road building has accelerated since 2010s. It averaged about per day in and per day in 2018–19. The country's target is to build of highways per day.
