The government of Bihar has unveiled plans for three new riverfront expressways spanning 220 kilometres along the Ganga and Gandak rivers. This ambitious project is set to revolutionize transportation and regional connectivity in the state, with long-term implications for the real estate sector.
Proposed Corridors
The three four-lane expressways are:
- Vishwamitra Path: Approximately 90 km stretch from Maner near Patna to Buxar via Arrah. It will connect with the Purvanchal Expressway in Uttar Pradesh, significantly reducing travel time between Bihar and Delhi.
- Ganga Ambika Path: Spanning around 56 km between Bidupur, Sonepur, and Dighwara, this route will improve connectivity around the Patna metropolitan region.
- Narayani Path: Stretching roughly 74 km from Sonepur to Gopalganj along the Gandak river, it will connect northern Bihar with the East-West Corridor.
These expressways will link prime districts with major national transport corridors, strengthening Bihar’s connectivity with Uttar Pradesh’s Purvanchal Expressway and the East-West Corridor.
Current Status
The Bihar State Road Development Corporation has initiated preliminary processes, including Detailed Project Report preparation, land acquisition studies, and other clearances. The projects will be executed under a Public-Private Partnership model.
Impact on Real Estate
Connectivity is a key driver for real estate development. These expressways are expected to transform peripheral areas into attractive locations for residential and commercial projects. Historically, expressway-led developments have created new real estate hotspots in states like Uttar Pradesh and Maharashtra. In Bihar, districts such as Patna, Bhojpur, Buxar, and Gopalganj are likely to benefit significantly.
If executed successfully, the 220-km riverfront expressway network could drastically transform Bihar’s development map and boost the real estate sector. Sources include a MagicBricks report and project details from the Bihar State Road Development Corporation.
