To "go down a road" is commonly used as a whole phrase! You could also use "path" instead of "road." It means to do something in a particular way. Ex: I tried to reason with him, but I don't want to go down that road again. He was very defensive. Ex: She went down the path of dentistry instead of her passion, art. Ex: I'm not sure what path to go down.
