Caption reads: The new 4.5-mile circular track at General Motors' Milford, Mich., Proving Ground arcs through the right half of this aerial view showing the central part of the 4,011-acre test area. The new banked circular track completely surrounds the older "ride-and-handling loop." Modern bridge-overpasses (center), incorporating the latest highway safety engineering concepts, connect the circular track and northern half of the proving ground with other test areas to the left.
