This isn’t Mill Road related, however a good source of photos of Cambridge past is worth recording.
In 1971, the late Peter Soar, a Cambridge solicitor and keen amateur photographer, set about recording the last days of the parts of Cambridge city centre destined to be demolished to make way for major redevelopment. He also photographed the area during construction and after most of it was completed.

On the same web site is a series of photos taken of the Kite Area in 1981 before its conversion into the Grafton Centre.
