Yes, it has many bridges.. But this one was single line and had two big junctions on both sides.. Hajipur and Sonpur and trains used to wait on these stations sometimes for half hour to one hour.
Even the earlier bridge had two lines, but one of them was MG.. And somewhere around last year i saw that the track was being removed. I thought that another line will be built on same bridge, but in one and a half year it was built upto this level and by seeing the speed of Construction I can say that it will take at the most 2-3 yrs for completion..
