which don't exist now

Hi, everyone. I know the bold is correct, but I feel it isn't good style. Could you make it better?
Once passing the security checkpoints, passengers will see some shops, which don’t exist now.
(Please check the picture I attached.)

Once through the security checkpoints, passengers will see some shops, which the airport currently doesn't have.

Thanks. If I use 'security' instead of 'security checkpoints', do I still need the definite article?

No. That would be incorrect.

You can't see things that aren't there.

The plan shows shops after passengers have passed through security. These shops are not there yet.

I think it is strange to say you will see things which are not there.

Not if you are discussing the expansion IMO.
