Patna: A long-awaited traffic overhaul in southern Patna is nearing completion, with the Karbigahiya roundabout poised to connect four major flyovers and reshape movement across the state capital.
Once finished, the junction will link routes from Mithapur, Chiraiyatand, the New Bypass and Sipara, offering more direct travel and reducing chronic congestion in some of the city’s busiest neighbourhoods. Officials say the project, which has been pending for years, is expected to bring relief to millions of residents who commute daily through the area.
A flyover between Karbigahiya and the New Bypass was completed three years ago but has remained largely unused because the roundabout required to integrate it into the wider road network was not in place. With construction of the roundabout now in its final stages, vehicles will soon be able to travel directly to the New Bypass, easing pressure on the railway station and Kankarbagh corridors.
As part of the redevelopment, a 490-metre, two-lane elevated road built on a steel frame is being constructed to connect the Karbigahiya roundabout with the Chiraiyatand bridge. Foundations for the structure have already been laid. The descending ramp from the Chiraiyatand bridge is also being modified, with additional structural work under way to facilitate smoother traffic flow. Once operational, the link is expected to significantly cut travel time between Station Road and Mithapur.
Meanwhile, work continues on the Mithapur–Sipara elevated corridor, which will extend to Mahuli via Sipara. Authorities anticipate completion within the next eight months, with traffic potentially beginning by October. Construction between the Chanakya Management Institute and the New Bypass is progressing, while the stretch from Sipara to the northern side of the New Bypass is close to completion.
At the heart of the scheme is a single convergence point at Karbigahiya, where the New Bypass flyover, the Chiraiyatand elevated road and the corridor from Mithapur will meet. The integrated design is intended to enable uninterrupted movement from the Mithapur flyover towards Kankarbagh, Gandhi Setu and Gulzarbagh.
For residents of south Patna, the project represents more than a new set of roads. It marks a structural shift in the capital’s traffic management, with its effects on commuting patterns likely to become visible in the coming months.
