What is another name for the Bifrost?

Excuse me, could you clarify something for me? I'm quite intrigued by the term "Bifrost" and I was wondering if there's another name that it's commonly referred to as within the realm of Norse mythology or perhaps in other cultural contexts? I'm particularly interested in learning if there's a synonym or an alternative term that captures the essence of what Bifrost represents. Could you please enlighten me on this matter?
