Yep, cul-de-sacs should just end in a dead end (with an end node).

There are many cul-de-sacs in CT that either end in a roundabout or loop road. Just clean them up with you see them...

Even then, doing so is questionable... The roundabout (or even a loop road can cause routing problems. Have a permalink?

He did that a while ago... and it's still going to mess with routing...

I'm going to change it to a dead end... If it starts generating problem reports, then we can change it to a loop road (but don't forget the extra junction)..

I have seen one where a roundabout was needed because it was so big with a huge island in the middle.

Even then, I don't think the driver needs it. To me, a roundabout is a fairly large circle with more than one exit.

That's pretty damn big!!

Mea culpa.

I have been correctly creating cul-e-sacs where roads end in a loop without an island (and have deleted more poorly created loops than I can count). Where there is an island however I was creating a loop to more accurately represent the geography of the roads. I will stop doing this and delete any I come across moving forward if this is not correct.

If large loops are ok, we should create a rule of thumb to determine when to use a dead-end segment vs a loop so we have consistency.

I just saw it today when I was doing US-1. I usually clean them up as I see them but I left that one alone, let me see if I can find it again.
