ELI5: How do filmmakers get major towns/roads for use in their movies?

After hearing about the filmmakers blowing up a bus on Lambeth Bridge near Parliament, I was wondering how the people who make the movies manage to close off such major roads like Lambeth Bridge, and get permission to do such stunts that could scare people? If it's involving money, which it almost certainly is, is anyone able to provide a rough guide of what they pay approximately? Thanks.

Oh yeah, it involves money.

You have to buy a permit from the city for permission to close the street, *then* you have to pay an off-duty cop (or for bigger productions, several of them) to direct traffic and enforce the closure.

Many productions actually shoot outdoor/city scenes in different cities, like Chicago or Detroit, and make it look like NYC, since NYC permits are outrageous.
