Detroit street location from the past.

[highjinx2]

I cropped and enlarged the street sign I found in a picture from Detroit that had no dating.
The street sign is of Grand River and Westlawn Blvd; I attempted to find it on current maps and the few maps I have of the past.
Does anyone have any idea where Westlawn Blvd. is or was located at?
Thank you for any response.
