Through the issue, which opened at the London Stock Exchange, NHAI aims to raise Rs 5,000 crore. It was launched by Union Minister Nitin Gadkari.
The proceeds from the rupee-denominated offshore bonds would be used for India's infrastructure projects.
"India gives the highest priority for infrastructure development. Our economy is the fastest growing in the world. NHAI is a flagship organisation, with AAA rating and we have many big projects to offer," Gadkari said at the London Stock Exchange market opening ceremony.
The transaction marks the largest ever five year issuance and the largest inaugural transaction in Masala Bond market, the official added.

The bond issue has attracted investors from across the spectrum with Asia contributing 60 per cent of the subscription and the balance 40 per cent coming from Europe.
Further, 61 per cent of the amount comes from the fund managers/ insurance, 18 per cent from the banks and 21 per cent from the private banks.
"The total infrastructure picture in India is changing very rapidly and we need financial support from international investors. We can guarantee that all our projects are economically viable, with good rate of return," he said.
In reference to the progress already made, Gadkari pointed to a hike in road construction figures, from just 2 kilometres per day when he took charge of the transport ministry to 23 kilometres a day at the end of March this year.
The government's target is to increase this length from 96,000 kilometres to 2 lakh kilometres, he said.
"The minister is someone who is a visionary, who gets things done. We are now on a roll with Masala Bonds. London is the financial centre of the world and the right place for more Masala Bond issuances," said Alok Sharma, the Minister for Asia in the UK's Foreign and Commonwealth Office (FCO), at the ceremony.
"This is a symbolic transaction for a number of reasons. We are hoping it would be the world's largest-ever Masala Bond. This bond will support the largest road building and transport infrastructure programme in the world. There is a huge appetite for investments in Indian infrastructure and confidence in the Indian economy," said Nikhil Rathi, CEO of London Stock Exchange plc, who described Gadkari as a "reformer and innovator."
According to the London Stock Exchange, there are 38 Masala Bonds currently in the market, raising around 5 billion dollars.
