It was built at a cost of K37.2 million.
City Manager Bernard Kipit says the Magani Crescent road will improve the heavy flow of traffic during peak hours.
The road connects Waigani from Gerehu via the late Sir William Skate highway.
Kipit also hinted that a four-lane road will be built from Pitpit Street to the highway, making Morata an investment and development hub.
This project was made possible through a Bank South Pacific loan, while the name of the road will be changed at a later date.
