Cant zone certain squares but can still plop on them, whats going on?

[nonessentialnoodle 2]

Ive got a small piece of land in my downtown which I cant seem to zone. Any thoughts as to why? Is this a bug with any solution? I know your probably thinking its to do with the highway infrastructure, but as the second picture shows I can still place things on the blank spaces, just cant zone them. So whats going on? Any thoughts?

Thanks!

What happens when you try to zone? Does the highlight turn red, or does nothing show, or something else?

Have you tried dezoning the area first? Does the same thing happen with other zone types?

I've seen this before near Maxis Highway diagonal interchanges and I have no idea what's causing it or how to solve it. De-zoning doesn't seem to work there...

Have tried de-zoning and doesnt help, its the same with all zone types, they just show up empty not red or anything. My instinct is that its related to the on/off ramps but then how come I can still place plops in it? Perhaps ill try demolishing the junctions and see if it still happens.

Edit:

Nope tried demolishing everything surrounding the area and it still has the same problem. Any other ideas or insight?

Make it a park, and forget it.

What happens when you place the interchange AFTER you zone? That would be important.

I appear to have fixed it, although I dont understand how.

By demolishing all the surrounding buildings and then building an airport then demolishing the airport I am able to zone the tiles again. I guess this is somehow related to the fact that the area was previously an airport.

But seeing as the area is in the middle of my Downtown i dont think I can afford to demolish it all! I'll have to look on the STEX for a small airport lot and see if that has the same effect.

Thanks for the help guys.
