Curved Ramps

How do you merge a ramp on to the main highway using corridors? Also how would you make that surface with two different alignments? I have my main road alignment and a ramp that comes on to it so the problem I'm having is making my 3d model with the road and surface combine.

Under Intersections, select Add Approach.

Todd, I'm not sure that this solution will work for the OP.  Could you provide more details?

Yeah, i totally misread that.  Most likely going to have to manipulate the corridor with targets.

Marco, I did a class on this topic at AU2012.  If you have access to the class materials then search for my session.  It details a workflow which should work for your situation.

Another easy job for the Intersection Wizard.

If you are planning to start a new project and have similar situation you can create one long corridor with multiple baselines and multiple targets. This is good approach but I would advise it to seasoned users since there is very easy to get lost in the design. If you have two separate corridors next to each other, (It seems that it is the case here) there is no way to merge them.

I just did the real quick with the Intersection Wizard, but hopefully it gives you the idea. This is one corridor with two alignments.
