The main objective of this project is to widen and strengthen the existing four-lane road to six-lane divided carriageway. This project starts at existing 0+000km of NH-5A and terminates at existing 76.646km. It passes through the three districts of Odisha and is to be developed as partially access controlled facility with provision of service roads, interaction, underpass and flyovers.

The expansion encompasses 14 major bridges with 11 vehicular and 16 cattle-pedestrian underpasses. A 54.53km length of service road with 1 toll plaza and 53 bus bays has also been proposed in the final detail design report.

The major challenge was to make alignment in such a way so that bare minimum structures are taken for land acquisition. An area of 7.2km in Paradeep town which is thickly populated and falls within the proposed Right-Of-Way alignment was adjusted to minimise the land acquisition. Due to the physical limitations of widening to six lanes, a four-lane bridge for one carriageway and new three-lane bridge were proposed.
