I would like to set up my templates using ORD (open roads designer) for the end conditions to tie into the existing pavement on the topo file.
I figured it out through training thanks
In order to tie existing pavement to corridor
Corridor > Edits > create point control > add start and end station > click on the corridor point you'd like to control > click the point you'd like to tie into
Video on where it goes into more detail via Bentley Training as mentioned from commenters:
Modify the Corridor
