I'm trying to model a U-Turn as you can find in attached picture. I think it should be done by intersections tools (i.e. 2 different intersection) but unfortunately curb return alignments and profiles doesn't work properly!!
and another question:
after U-Turn I have a median with varying width. I tried to use marked point and link to marked point subassemblies to model it. but the link didn't connect 2 corridor (i.e. North ands outh ways)
