Tough to answer my question brother

No need of pre booking. Just go around 9am- 12pm or in the evening,buy the ticket ( Rs.5 from millennia park to howrah), hop on it and enjoy the view of Howrah.Ferry is the another transport to locals just like bus and tram. So it is available most of the time. Have a nice journey...

howrah Bridge from howrah railway station is at walking distance.

To see Howrah bridge from ferry, one has to take Bagbazar bound ferry surely at evening 6:30-7:30 approx.

Take a launch ride starting from Fairlie (ghat) up to Bag Bazar (ghat) with stopover in between should be worth the total time. for a two way trip should be max 45 minutes. One can get a nice glimpse of the bridge from within the river and of course the Kolkata river side from the other side. However, one should add commuting time up to Fairlie from last point.

Reach time is depend on traffic.From airport to Howrah bride is approx 26 km,My suggestion book a ola or uber cab & tell the driver go from shortcut root.They will do it because of rating.

The Howrah Bridge was not the out come of single engineer. Several steps and policies and planning with some groups & teams this was possible. In 1862, the Government of Bengal asked George Turnbull, Chief Engineer of the East India Railway Company to study the feasibility of bridging the Hooghly River . In 1921 a committee of engineers named the 'Mukherjee Committee' was formed, headed by Sir R.N. Mukherjee, Sir Clement Hindley, Chairman of Calcutta Port Trus,t and J. McGlashan, Chief Engineer. They referred the matter to Sir Basil Mott, who proposed a single span arch bridge. In 1930 the Goode Committee was formed, comprising S.W. Goode as President, S.N. Mallick, and W.H. Thompson, to investigate and report on the advisability of constructing a pier bridge between Calcutta and Howrah. Based on their recommendation, M/s. Rendel, Palmer and Tritton were asked to consider the construction of a suspension bridge of a particular design prepared by their chief draftsman Mr. Walton. The Braithwaite Burn and Jessop Construction Company Limited was awarded the construction contract.

George Turnbull, Chief Engineer of the East India Railway Company was the engineer, as per a quick Google search.

The bridge was designed by one Mr.Walton of M/s Rendel, Palmer & Triton. Engineers were from the local howrah company "The Braithwaite Burn & Jessop Construction Company" Howrah bridge was a replacement of Pontoon Bridge in order to resolv the issue heavy traffic.
