Yes outside the boundary - looks like a vehicle test track. Located in what is now Vauxhall Way. Just for orientation the Spittlesea hospital buildings are in the centre - flying club just north east of that. The bend they sit on is now passing the Monarch headquarters and the lane winding along the bottom is Dane Street which was cut by the runways and reappears on the south east side.
Out of interest the photo was taken in 1947 by a 82 Sqdn aircraft flying at 16,400ft.
