Overview

  • A portion of the upper deck developed a crater and multiple cracks after persistent rain and urban flooding stressed Patna’s drainage network.
  • Bihar Road Construction Department and Bihar Rajya Pul Nirman Nigam Limited say the superstructure remains intact and repair work on the bituminous wearing course has already begun.
  • The double-deck corridor spans 2.2 km with two 8.5 m-wide levels, built by Bihar State Bridge Construction Corporation for ₹422 crore and inaugurated June 11 to ease Ashok Rajpath congestion.
  • Public criticism has resurfaced over infrastructure quality and accountability after earlier viral safety alarms and a history of bridge failures prompted a state maintenance policy.
  • As part of Patna’s smart-city plan, the flyover links key hubs and upcoming metro stations, highlighting the challenge of ensuring resilience in rapidly delivered urban projects.
