Rajendra Setu (Hindi: राजेन्द्र सेतु) (also known as Rajendra Pul and Mokama Bridge) across the Ganges was the first bridge to link North Bihar and South Bihar.
The road-cum-rail bridge near Mokama in Patna district was inaugurated by Dr. Rajendra Prasad, President of India. It is about 2 kilometres (1.2 mi) long and carries a two lane road and a double line railway track. It was opened in 1959.
A four-lane road bridge, carrying NH 31, parallel to the existing rail and road bridge, has been planned.
