AmE speakers often use be going to (and the informal short form gonna) when giving street directions, which is not a typical use in BrE. BrE speakers normally use imperatives (with and without you), and present simple or future forms with will:
[AmE]
You’re gonna go three blocks and then you’re gonna see an apartment building on the left with 1228 above the door.
[BrE]

Great. Thanks very much.
