Situated in the central part of Bihar on the south bank of river Ganges, the project road connects with four national highways (NH-83, NH-19, NH-30A and NH-31) providing vital interstate linkage.  This project involved the upgradation from two to six lanes of Patna-Bakhtiyarpur Section of NH-30 in the state of Bihar from 181.300km to 231.950km under the Design-Build-Finance-Operate scheme.

The expansion encompasses two major intersections, 11 minor junctions, a major bridge having three spans of 40 metres at the Punpun River (one of the tributaries of the Ganges) and a flyover cum Road over Bridge.

The road alignments were designed in such a way that bare minimum structures would go under land acquisition as the stretch passes through terrains that are used mostly for agriculture.
