Audio slideshow: Houses and highways

In the decades following the end of World War II, suburban sprawl started to stretch out from US cities - alongside new, fast, multi-lane freeways.

Here, Professor of International History David Reynolds - from the BBC Radio 4 series America, Empire of Liberty - charts the growth of the suburbs, and explains why skin colour prevented some families from starting a new life.
