"All traffic will be below or high above ground when brought within city limits. In most cities it will be confined to broad subways or tunnels, well lighted and well ventilated, or to high trestles with moving-sidewalk stairways leading to the top. These underground or overhead streets will teem with automobile passenger coaches and freight wagons with cushioned wheels. Cities, therefore will be free from all noises."
- John Watkins, predicting what life would be like in 100 years in the pages of the Ladies Home Journal, 1900.
