 Georgia Tech is sometimes jokingly referred to as the "North Avenue Trade School" in reference to this street, the largest thoroughfare near its original center.When North Avenue was first constructed, this arrow-straight avenue followed the lines between the already-surveyed land lots in Fulton County, Georgia, and it was very near to the original northern city limits.In fact, there was a line of fortifications of Confederate Army dug just north of North Avenue for the Siege of Atlanta in 1864.
