About
Munger Ganga Bridge — officially Sri Krishna Setu — is a 3.692 km rail-cum-road bridge across the Ganges at Munger in Bihar. Sanctioned in 2002 with the foundation stone laid by then-PM Atal Bihari Vajpayee, the bridge was opened to road traffic in March 2016 and to rail traffic in 2022.
The project endured a 14-year construction window — atypical even for Indian bridge projects — driven by funding gaps, contractor changes, and unusually deep alluvium under the Munger reach of the Ganges (some piers sit on open wells sunk to over 50 m depth). The cost ballooned from an initial ₹500 crore to ₹1,500 crore.
The bridge provides Bihar's second-shortest North-South rail link (after the Patna-Pahleja JP Setu), connecting the South Bihar railway main line to the North Bihar lines via Khagaria. Road traffic is part of NH-333A. The bridge has 18 main spans of 124 m each across the Ganges channel and shorter approach spans on both banks.
A distinctive feature: the bridge integrates a Customs check-post mid-bridge for cargo crossing the river — a rare feature in Indian bridge design, since most river bridges have their toll/customs facilities at the approach abutments only.
