I've been wondering for a while if TOD could work around freeway interchanges for a few reasons.
Cluster development already happens around interchanges, including ones that are not near any settled places. With that in mind, I noticed that Westlake, OH has a TND type retail complex just off of I-90 (offices/apartments on top of stores like you would normally see in an indoor mall with on street parking and little other surface parking.) The neighbourhood is definitely not served by any transit other than buses. While the whole area had a rather "fake" feel to me, I couldn't deny that it's superior to the normal development that sprouts up around highway interchanges.
Is TOD around interchanges happening anywhere else? For areas that lack any transit beside buses, I'd rather see this kind of development happen. I don't want to wait until light rail or whatever comes to an area, which could be years. If the TOD around the interchanges happens first, the area might even be more ready to be served by transit, be it by bus or something on rails.
