I have 1 small trade depot which has 1 coal storage, 1 ore storage and 1 fright storage. and its locked to cannot add more.

I have 1 big trade depot which only has 1 Fright stoarge, and I cannot add more storage because it says "NOT APPROVED" ---> What should I do.

Also, my whole city has High TECH level, univercity running at full and 1 Electronics HQ, which earlier used to say NEED ALLOY Import from global, but somehow I fixed it with Recycling center.

But Eletronix HQ now has produced too much and its OUTPUT STORAGE is full. Same problem now arising to my factories "Closing cus of no places to ship fright."

How can I fix my FRIGHT SHIPPING problem ? I have no place for Municipal airport.

I have 10,000,000$+ money and Income is 13500$ per/hr. Poppulation is 100,000.

And, to build GREAT WORKS I need resources though I have money. Other 3 users in my region are all gona in excessive expenses and high population.
