We had one of these interchanges installed near where I lived in Georgia. For years traffic in that intersection was a nightmare. After they put in the DD you could zip through in no time flat. It’s a stupid sounding idea that works brilliantly.
Ashford-Dunwoody at I-285? It works great, though I still avoid the area on general principals most of the time. I have home field advantage, I can pick and choose routes.
I love all the nay-sayers who’ve probably never transited a DD interchange.
My guess is you don’t live there now

It costs much less to build, takes much less time to build, has higher throughput, and is safer.
I noticed the first one added a wide sidewalk, too, where there was none with the traditional design.
