hitomichan1- I am having the same problem. It seems to have started recently. I have zoned landfills in several different cities, new and existing, with same result. my existing landfills appear fine, but i can't zone new ones. very strange. Yes, I too have multiple road connections & neighbor connections. This was my first stop in search of answers.... edit.... i found the answer to my problem... I didn't have any zones yet. once i zoned something, it went away... see: https://www.simtropolis.com/forum/messageview.cfm?catid=22&threadid=87282
