Problem connecting track when there are several vertexes

[radionut44]

I am attempting to remove a turn from the top of a helix and attach an exit track to the new “end”. The problem is there are also vertexes for the lower turns in practically the same position, even when I zoom in. Even by setting the vertex for the “exit” track to exactly the same height as the “end” of the helix I cannot keep the exit track from being pulled to one of the lower tracks of the helix.
Is there a trick to this I should learn? When there are only 2 vertexes there is no problem getting then to join.

Move one slightly out of the way, then join the track to the end. Once done, move the other track back.

Can you do the opposite, like a bridge? Instead of joining the exit track to the helix, join the helix track to the exit track?
