A day before it was to be inaugurated by Bihar Chief Minister Nitish Kumar, a portion of canal built at the cost of Rs 389.31 crore in Bhagalpur collapsed on Tuesday. Bihar Chief Minister Nitish Kumar was scheduled to inaugurate the canal scheme, aimed at providing irrigation facilities in the state and neighbouring Jharkhand.

The first administrative approval to the project was provided in 2008 involving a cost of Rs 389.31 crore.
