What do Americans call at junction?

Excuse me, but I'm curious to know something. I've come across a phrase in a conversation recently that I found quite intriguing. It mentioned something about Americans having a specific term for a certain location. Specifically, it said "What do Americans call at junction?" Now, I'm familiar with the word "junction" in general, referring to a point where two or more things, like roads or rivers, meet. But I'm intrigued by the idea of there being a particular American term for this. Could you perhaps shed some light on this for me? Is there indeed a unique term that Americans use to describe a junction, and if so, what is it?
