Where is Upper Wentworth strett/road located in the town?

Well "Upper" means it's up on Hamilton Mountain. All north/south streets at Hamilton Mountain are "Upper", expect two streets. Upper Wentworth is right along Limeridge Mall. It's between Upper Sherman and Upper Wellington.

Hope that helps.

steeltown has explained well... but you can also use this map. it may help more to you.
