Patna: The Danapur–Bihta–Koilwar elevated corridor, one of Bihar’s most significant road infrastructure projects, is scheduled for completion by June 2027, with nearly 45% of construction already finished, officials said.
Arvind Kumar, project director of the National Highways Authority of India (NHAI), shared the update during an inspection of the project site in Danapur on Wednesday. He said work on the remaining 55% of the corridor would be accelerated to meet the deadline.
Stretching about 25 km, the elevated corridor is being built at an estimated cost of Rs 1,969 crore. Once completed, it is expected to significantly improve traffic flow between Patna and western Bihar, reducing congestion, travel time and road safety risks that have long plagued commuters on this route.
Before construction began, the corridor area was known for heavy traffic, frequent jams and unpredictable travel times. Office workers, students, patients, traders and transport operators often faced long delays, particularly during peak hours.
Kumar said the project would also improve connectivity to Bihta Airport, nearby industrial zones and major educational institutions, making daily travel more efficient for a wide range of users.
He acknowledged that building the corridor through densely populated areas had posed the biggest challenge. Managing traffic during construction, working within limited space and dealing with weather-related disruptions required careful planning, he said.
“These challenges were addressed by executing the project in phases to minimise inconvenience to the public,” Kumar said, adding that close coordination with the local administration, police, engineers and other stakeholders helped resolve issues quickly.
Strict adherence to safety standards was maintained throughout the construction process, he said, with adjustments made to work procedures to accommodate local needs and ensure that public interest remained a priority.
