Hello, and welcome to OSM.

It looks like you are trying to make fairly complicated changes to infrastructure, but I see that you are using the simple online editor on osm.org (which is called iD), which is definitely not suited for such actions.  The summary of this changeset shows warnings in at least 4 different categories, and virtually every bus route going to the airport has been broken when you erased some roads and did not rebuild proper chaining for buses.

I am afraid this will call for significant repairs in OSM data.  I will try to see what we can do.

Can I suggest you to learn a little more how to edit OSM by doing smaller, less significant, changes for your first contributions.

Have a nice day.
