Gandhi Setu was built to connect Patna with Hajipur. The bridge also connects north and south Bihar. The bridge is 5450 meters in length and the longest in the world. Gandhi Setu has helped in better traffic management and speedy transportation in the entire region.
Mahatma Gandhi Setu stands on forty piers and for better navigational purposes the span arrangement has been done in such a manner that it does not affect the movement of ships and big boats. To accommodate free movement of ships, height has been kept optimum except for the last few spans on the Hajipur side, which covers a length of 305 m. An excellent specimen of better plan and execution, Gandhi Setu has served an example.
