Cloverleaf U Turns & Second Chances?

[Vocalicacorn187]

Where I live we have no cloverleafs. Their are only a few left in the province and slowly the last of them are being removed and replaced with parclos. I will say though that it is nice to be able to just do a U-turn with having to go through lights.

To take this to the extreme, you could just have four loops without the outer ramps, with signs indicating to exit unless you want to stay on route X. 

This comes close, although right turns are allowed at the ramp ends.

Ah yes, the "everyone goes through the tollbooth" design of Kentucky parkways which stands as a remnant after tollbooths are gone.  Audubon Parkway has similar (https://goo.gl/maps/toiHHFw7TvjmcBd36) right down to the labelscar of old signage mounted on the bridge for tollbooth lanes.  Cumberland Parkway at US 127 used to be the same but was recently made into a conventional diamond (but with the labelscar still on the overpass).
With traffic stopping to pay a toll, the short weave was no big deal.  At regular speed, the loops-only design fails having such a tight weave.

Wildly enough OK still has this at a few locations, though I know they're in the process of going all electronic statewide.

Quebec also used the cloverleaf toll configuration at some locations (especially along Autoroute 10) but the toll plazas were located several feet away from the overpasses, not directly underneath them. Judging by this Street View it looks like they're finally removing the loops here (the tolls were removed decades ago)
