I had to deliver a bicycle to Carmel, Indiana (northeast of Indianapolis). Getting there on the under-reconstruction I-70 was so brutal I took back roads home. It’s been at least a decade since I was up there, man have things changed. Every other intersection is a roundabout – it’s downright dizzying. And then BAMB! you’re right in the middle Amish country sharing the road with horse-drawn carriages. I came up on a traffic light and before I knew it I was in the middle of a strange, interesting intersection and I was not real confident I was going through it properly. I just went with the flow and quickly found myself on the I-69 North, like socks on a rooster. It was actually pretty smooth and quick.
I’ve read about them – “Compound Inverse Double Divergent Inverted Diamond Interchange” or something like that. When I got home, I Googled it - and what do you know, the first picture that popped up was the very intersection I experienced! I guess they are still relatively rare.
Are there any around you?
I was coming from the West (right of the picture) and turning on North onto I69 (bottom of the picture).
Now if they just replace the traffic lights with roundabouts we would never have to stop for anything.
