The Golden Quadrilateral is a highway network connecting many of the major industrial, agricultural and cultural centres of India. A quadrilateral of sorts is formed by connecting Delhi, Mumbai, Kolkata and Chennai, and hence its name. Other cities among the top ten metropolises namely Bengaluru, Pune, Ahmedabad, Jaipur, Kanpur and Surat are also connected by the network.

The largest highway project in India and the fifth longest in the world[citation needed], it is the first phase of the National Highways Development Project (NHDP), and consists of building 5,846 km (3,633 mi) four/six lane express highways at a cost of INR600 billion (US$10 billion).[1] The project was launched in 2001 by Atal Bihari Vajpayee under the NDA government, and was planned to complete in January, 2012.[2]

The vast majority of the Golden Quadrilateral (GQ) is not access controlled, although safety features such as guardrails, shoulders, and high-visibility signs are in use.

The GQ project is managed by the National Highways Authority of India (NHAI) under the Ministry of Road, Transport and Highways. The Mumbai-Pune Expressway, the first controlled-access toll road to be built in India is a part of the GQ Project though not funded by NHAI, and separate from the main highway. Infrastructure Leasing & Financial Services (IL&FS) has been one of the major contributors to the infrastructural development activity in the GQ project. Contents

History and costs

Then Prime Minister Atal Bihari Vajpayee laid the foundation stone for the project on 6 January 1999.[3]

In January 2012, India announced the four lane GQ highway network as complete.[4][5]

India's government had initially estimated that the Golden Quadrilateral project would cost INR600 billion (US$10 billion) at 1999 prices. However, the highway has been built under-budget. As of August 2011, cost incurred by Indian government was about half of initial estimate, at INR308.58 billion (US$5.2 billion). The eight contracts in progress, as of August 2011, were worth INR16.34 billion (US$280 million).[6]

In September 2009, it was announced that the existing four-laned highways would be converted into six-lane highways.[7] The expansion project was reported at various stages to be behind schedule, mainly due to land acquisition constraints and disputes with contractors which had to be re-negotiated.[8][9]

Sections of NH 2, NH 5 and NH 8 have now been prioritized for further widening to six lanes under DBFO (Design, Build, Finance, Operate) pattern and more sections would be six-laned in the near future. On NH 8 Six lanes work is completed...
