Okay, here's one for you... I've avoided trying to do anything with this mess...

We have grade level intersection of a dual carriageway (Cloverbar
Road) running roughly N/S, with two non-divided ways (Craigavon Drive
& Highland Drive) intersecting perpendicular to the first way. Both
Craigavon and Highland have decorative dividers separating the
opposing traffic lanes for about 100 meters either side of the
intersection. Right hand and left hand turns are allowed for traffic
moving in all directions, however traffic is not allowed to drive
straight across the intersection from Craigavon to Highland, nor
vice-versa.

How do you tag this intersection without making it look like a
complete dog's breakfast?

The thought process behind this is to keep through traffic out of
residential areas, but all it does for traffic that needs to get from
one neighborhood to the next, is that you have to detour through yet
another neighborhood in order to get turned around and back to the
intersection from a new direction. Not the smartest design concept in
my mind.
