JP Ganga Path Patna FAQs
JP Ganga Path, also known as Ganga Path or Ganga Drive, is a major riverside road corridor along the southern bank of the Ganga in Patna, Bihar. The main Digha–Didarganj corridor is about 20.5 km long and is designed to improve east-west connectivity across Patna while providing faster access to important locations along the riverfront.
The main Ganga Path Patna route runs from Digha in western Patna to Didarganj in the east along the southern bank of the Ganga. The corridor passes through or connects major locations including Digha Ghat, A.N. Sinha Institute, PMCH, Krishna Ghat, Gay Ghat, Kangan Ghat, Patna Ghat and Didarganj.
The original JP Ganga Path corridor from Digha to Didarganj is approximately 20.5 km long. The project includes elevated and at-grade sections along the southern bank of the Ganga, together with connecting roads and access points to major parts of Patna.
The JP Ganga Path project is a major road infrastructure project being implemented by Bihar State Road Development Corporation Limited (BSRDCL). The Digha–Didarganj corridor was developed as a four-lane riverside road to improve connectivity between western and eastern Patna and reduce dependence on congested inner-city roads.
Yes. The completed JP Ganga Path has been opened progressively in sections, and the Digha–Kangan Ghat stretch is operational. The completed corridor has significantly improved east-west movement along Patna's northern riverfront. Additional connectivity and extension works are continuing around the wider project.
JP Ganga Path connects western and eastern parts of Patna through a riverside corridor. Major connected locations include Digha, Digha Ghat, A.N. Sinha Institute, PMCH, Krishna Ghat, Gay Ghat, Kangan Ghat, Patna Ghat and Didarganj. The road also has connections toward Atal Path and other important city roads.
The main Digha–Didarganj JP Ganga Path has substantially progressed into operational use, while supporting connectivity works are still being developed. Current associated works include the four-lane Patna Sahib Railway Station–Patna Ghat connection, additional connectivity roads and extensions of JP Ganga Path toward the Digha–Sherpur–Bihta and Koilwar Bridge corridor.
Recent project developments include construction of a 1.55 km four-lane road connecting Patna Sahib Railway Station with Patna Ghat, which is being developed as part of the wider JP Ganga Path connectivity package. Bihar's ongoing-project records also list further JP Ganga Path extensions and associated connectivity works.
Ganga Path and Ganga Drive are commonly used references for the riverside road corridor along the Ganga in Patna. The formal project name used by Bihar government agencies is JP Ganga Path, particularly for the Digha–Didarganj corridor.
JP Ganga Path is a major four-lane riverside urban road corridor rather than a conventional access-controlled national expressway. It was developed to provide faster movement across Patna and improve connectivity between major city areas along the southern bank of the Ganga.
The JP Ganga Path provides connections to important locations and roads including Atal Path, Digha, PMCH, Gandhi Maidan-area access, Krishna Ghat, Gay Ghat, Kangan Ghat, Patna Ghat and Didarganj. The project also includes additional connectivity roads designed to link the riverside corridor with surrounding parts of Patna.
The JP Ganga Path begins near Digha Ghat and runs eastward along the southern bank of the Ganga before reaching the Didarganj area near old NH-30. Along the route, the corridor provides access to major riverfront locations including PMCH, Gay Ghat and Kangan Ghat.
The core JP Ganga Path Digha–Didarganj corridor is substantially operational, while several associated connectivity and extension projects remain under implementation. Bihar government project records continue to list works connected with JP Ganga Path, including Patna Sahib–Patna Ghat connectivity and the extension toward Sherpur–Bihta and the Koilwar Bridge approach.
JP Ganga Path provides an alternative high-capacity route along the Ganga, improving east-west connectivity and reducing travel through congested central Patna roads. It also improves access to major destinations such as PMCH, Patna City, Kangan Ghat and Didarganj while supporting future regional road connections.
A major planned extension is the Digha–Sherpur–Bihta corridor up to the approach road of the Koilwar Bridge. The proposed extension is approximately 35.65 km long and is intended to extend the JP Ganga Path corridor westward from Digha toward Bihta and the Koilwar Bridge approach.
