U turns modelling & marked point

Dear colleagues,

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)

I'd forget the intersection tools and do this manually with a corridor and a few baselines and some good assemblies.

have you tried basic lane transition in place of marked point and link to marked point?

I is doable with the intersection tools.


Attached is a link to a drawing with the intersection constructed as per your picture.
