New Delhi, June 16 -- On May 6, Interise Trust-an infrastructure investment trust (InvIT) jointly controlled by two Canadian pension funds-handed back a four-lane road constructed on the build-operate-transfer model in Maharashtra to the National Highways Authority of India (NHAI) after its toll concession period ended. In August, the InvIT will transfer one more. That will bring the number of highways it would have transferred since 2022 to four.
