As of June 1, 2025, numerous vital highway infrastructure projects in Bihar have been awarded but are yet to commence. These projects span greenfield corridors, strengthening and maintenance of existing national highways, construction of flyovers, and the development of bypasses. These initiatives are part of a broader push to enhance road connectivity and streamline transportation in the state.
Among the significant projects, two contracts have been awarded for the strengthening and major maintenance of the Muzaffarpur–Darbhanga–Purnea section of National Highway 27. Sheeraj Projects Private Limited has secured both packages — the first covering the stretch from Km. 156.456 to Km. 285.007 (128.551 km), and the second from Km. 0.000 to Km. 145.646 (145.646 km). Both contracts were awarded on March 29, 2025.
In another major development, Dhariwal Buildtech Limited has been awarded the contract for constructing the Kishanganj–Bahadurganj greenfield section (22.6 km), with the Letter of Award (LOA) issued on March 18, 2025. This project is expected to provide improved regional connectivity in the northeastern districts of Bihar.
