Calculate Elevation of Endpoints for Network

Good afternoon all!


I have ArcGIS 10.3 and ArcInfo License.


I am trying to improve my organizations network dataset by further defining connectivity. After following the steps here I got to step 20 and realized the roads file we use does not have elevation or z-levels. I understand you can use the feature vertices to points, then extract values by points (extract z-value from raster to endpoints of roads). However, I am confused as to how this would better define connectivity.


For example, at the point where 2 roads intersect, wouldn't that endpoint (the intersection) have only 1 elevation value? Am I supposed to get the z-value for one of those roads at a buffered distance away from the other?


In the end I want to be able to model overpasses and underpasses, which our network does not do currently.


Thank you!
