The National Highways network of India is a network of trunk roads that is owned by the Ministry of Road Transport and Highways. It is constructed and managed by the National Highway Authority of India (NHAI), the National Highways and Infrastructure Development Corporation (NHIDCL), and the public works departments (PWDs) of state governments. NHAI was established by the National Highways Authority of India Act, 1988. Section 16(1) of the Act states that the function of NHAI is to develop, maintain, and manage the National Highways and any other highways vested in, or entrusted to, it by the Government of India. These highways as of December 2018 measure over 131,326 km (81,602 mi).[1] The Indian government led by PM Modi has vowed to double the highway length from 96,000 to 2,00,000 km.[2]Template:MOS:DIGITS
As of June 2018, 27 km per day of highway construction has been achieved which is unprecedented in Indian history.[3]
In India, National Highways are at-grade roads, whereas Expressways are controlled-access highways (mostly six-lane or above) where entrance and exit is controlled by the use of slip roads (ramps) that are incorporated into the design of the highway. The at-grade national highways do not have shoulder lanes.
The National Highways Authority of India(NHAI) is the nodal agency responsible for building, upgrading, and maintaining most of the National Highways network. It operates under the Ministry of Road Transport and Highways. The National Highways Development Project (NHDP) is a major effort to expand and upgrade the network of highways. NHAI often uses a public-private partnership model for highway development, maintenance, and toll-collection.
While National Highways constitute 1.8% of Indian roads, they carry 40% of the traffic.[4]The majority of existing National Highways are two-lane roads (one lane in each direction), though much of this is being expanded to four-lanes and some to six or more lanes. Some sections of the network are toll roads.
Bharatmala, a centrally-sponsored and funded road and highways project of the Government of India [5] with a target of constructing 83,677 km (51,994 mi)[6] of new highways, has been started in 2018. Phase I of the Bharatmala project involves the construction of 34,800 km of highways (including the remaining projects under NHDP) at an estimated cost of ₹5.35 lakh crore(US$74 billion) by 2021-22.[7]
