Go to Analyze > Overpasses Check 
This is used to check for links that do not break at intersections or what could also be just a bridge. This may cause problems when generating routes or be deliberately. It is important that you only use this function without the z-levels being when creating the network.
At the end of the function the map will display the locations:
The points on the map mark the "Over Passes".
A browser is displayed with the link number and the position of the overpass along the link in terms of a percentage where 1 = 100% You can select a record from this browser and then use right click in the map window and then select "Find Selection" to move to that point on the map.
