On July 15, 2020, a portion of approach to Sattarghat Bridge (Ram Janaki Pul) in Bihar, India on Gandak River that was inaugurated a month ago collapsed after water flow increased in the river due to heavy rainfall. The main bridge of the Sattarghat Bridge plan is intact but a culvert (an 18 m long minor bridge) connecting the approach road to the bridge was unable to withstand the pressure caused by the rising levels of the river and was washed away.
