How to connect the disconnected curves

[Jay_B (Jay)]

Hello.
I’m trying to connect the part that disconnected to the road line that I brought from the drawing and make it a closed curve.
I would like to connect the part that disconnected like the green line in the first picture below like the second red line.

I tried to connect the closest point of each curve, but it didn’t work as I expected.
I would really appreciate it if anyone could help me or give me advice on these matters.
I’m sorry that I didn’t try many methods because I didn’t have enough skills.

I have attached the Rhino file below as well.

Thank you.

Thank you for your reply.
It’s really similar to the direction I want.

When I applied it, it was connected to only two places as shown in the picture below, but it was not applied elsewhere.

Of the two places that were applied, the way I really wanted it to work as shown in the picture below. Does it only work if there is a line that collides in a straight line?
