The centerlines should follow the centerlines, but where you have the fork,
I'll taper from just before the solid lines start to the start of the
physical separation.  The //// hashmarks on the shoulder indicating a no
travel/no stopping area make a handy reference.

I usually join it in where the //// hashmarks are on the shoulder just
after the end of the acceleration lane, tapering in from the end of
physical seperation.
