Using 대로
I am a little confused when it comes to 대로 it means main street but is there also another meaning, like grammar?

Question

Answer

This roughly means something like "just as" or "in accordance with"

Here's a Talk to Me in Korean lesson on it. http://www.talktomeinkorean.com/lessons/l8l18/

Answer

There are several meanings in it,
1. as a noun, "대로" means "main street" as you said,
2. as a linker,  "as" meaning, "-ㄴ대로",
e.g. 집에 도착하는 대로 전화해.
= Call me as you get home.
3. as an adverb, "in the same way",
etc,.....
