Non credo. Non ho nemmeno notato la presenza di cancelli agli ingressi che potessero chiudere il passaggio. Più di così non saprei.

assolutamente no

It's for free. You can just walk across the bridge

Yes sure! Just be careful of angry cyclist!

My personal favourite is to use google map, not only it gives you the direction but the train arriving time as well, hugely useful as you know New York train timing can varies especially if you missed the train

Aconselharia ir a região do Dumbo, próximo ao Time out Market e ao Brooklyn Bridge Park. Vai conseguir fotos ótimas da ponte com o skyline de Manhattan ao fundo. E não entendi se você está se referindo a alguma guia específica, mas indico muito muito os serviços do Rennylton da @rennytours_nyc . Ele é brasileiro, e oferece tours guiados, além de prestar também o serviço de transfer do aeroporto até o local de hospedagem.

It's free....no charges

no. The bridge for walking is elevated above the roadway and the roadway is a highway where there is no ability to pull over unless an accident. You can rent bikes at either end and ride if you want.

As a native NYer I would not try to park near the bridge. I would go to the hotel and take public transport- though it is a long ride. Try this- from JFK take the A train to High Street and walk either the Brooklyn bridge or even better the Manhattan bridge which leaves you in Chinatown. Walking to the village from either bridge is doable but very very long.

This is exactly what we did:) The others have given you good advice. We used Google maps to navigate the subway. Hit the little microphone symbol and then tell it "current location to (wherever you want to go) the Brooklyn bridge". Then select the transit choice (vs car, bike, walking). It will give you step by step instructions starting ]from entering the closest station to you (even which corner to enter) which trains are an option and how many stops there are. Once you get to Brooklyn the bridge is huge. Just walk towards it. We asked a police officer. He gave us a scenic route and a direct route and a great pizza place recommendation...Antonio's. When we walked in May heading towards Manhatten bikes occupied the right or NE side and pedestrians the opposite side . Watch those bikes (especially if you have kids)...they go really fast. Time will depend on how crowded it is and how much you stop to look and take pictures. Once you make it back to 911 memorial area use the new Oculus station to catch a train "uptown" to Times Square. Again use Google maps to pick train etc. We bought a one week Metro pass for 30.00 bucks plus 1.00 fee. Its easy... just go into a station to the machines. Follow the instructions or ask. There were plenty of friendly people willing to help:) It was our first time visiting NYC and the subway was a little intimadating at first but we quickly adapted. People were very willing to help so just ask if you are not sure what to do. Learn downtown means towards the 911 area and Uptown means towards Central Park/Times Square area. Have a nice visit.
