I've created a T intersection and have created the surface for the T corridor and the entering side road. The surfaces appear correct. When I create a surface for the main road, which has been split into two regions, the surface goes thru the T corridor. How do I create a surface that simply goes up to the T intersection and picks up again after the T intersection?
There may be a better way, but you can add a Hide boundary to your surface.

It seems like a workaround because you are making it so. During intersection creation choose to add the intersection to one corridor that consists of the two roads as suggested.
