This is a old post but I'm also faced with a similar problem in designing a intersection. Any ideas?

 

Thanks,

I had to dig for it, but try this old thread.

Ues the LanefromTaperedMedian SA's when you have medians in your roadway and you won't have to do all of these suggested pasting surfaces workarounds. They are designed to target the median alignments as is required with this design work. You can push the median across centerline, and have it collapse and disappear when you get past the median sections due to the median alignments being gone, just like LDD.

 

MatthewK suggested this deep into that old post, but no one seemed to listen.

great methods, Thanks. When using the LanefromTaperMedian SAs can you have curb and gutter on either side?

Yes, then I have my Code Style set up to vertically label Offset/Elevation at all of the desired flowlines across the Section.

 

It's a very nice and elegant way to go.
