i have generally tried to use about the same approach as you did to this
one, map what's really on the ground, and yes, you do end up with a lot
of turn restrictions. here is the newish SPUI in Latham, NY, which i mapped
shortly after it was completed a couple of years ago. i originally mapped
with stuff coming together, and afterwards decided that it really needed
to be done properly. i think the main reason to go into all the detail is
to insure routing engines have correct and complete descriptions of the
road network:
