The Central Government has approved the Muzaffarpur-Sonbarsa four-lane road project in Bihar, a significant boost to the state's infrastructure development. This crucial project is estimated to cost ₹3,590 crore. The four-lane road will connect Muzaffarpur district to Sonbarsa in Sitamarhi district, significantly reducing travel time and improving connectivity between these regions.

The project is a vital part of National Highway 77 (NH-77) and aims to streamline traffic flow in North Bihar, promoting trade and commerce. The road construction will not only provide better commuting facilities for local residents but also facilitate the transportation of agricultural produce and other goods, thereby boosting the regional economy. The project is also expected to generate new employment opportunities. The road will be constructed according to modern standards, with special attention to safety and efficiency.
