Roundabout Corridor HELP

[Jason.Ferrelli]

I have seen a few videos on how to make a roundabout corridor with the intersection tool, however I am having trouble coming up with a plan of attack for this one

It goes from a one lane to a two lane back to a one and two again, not to mention all the split islands
I guess I just need to talk out a few ideas where to start with this.

Any Ideas?

nice one, now that's a challenge, Crown? or cross slopes? you have center line profiles or back of curb? i think i would have 3 center lines with lots of construction lines for targets at the main intersection.

and check this out for the islands http://www.civil3d.com/2010/01/keep-your-curbed-islands-afloat/

wow very complexed roundabout. I just finished designing 2 roundabouts in the subdivision i was working on. If you trying to created the roundabout with the intersection feature you will only make your corridor parameters more complexed and drawing larger. I will look at it tonight and see what i can come up with to help you. Can you attached the drawing base or email me the drawing so i can take a look at it?

Just a quick note. It is not desirable to use bmp's due to their bloated
size. Notice this .png file.
