Cambridgeshire street list and map also describes it as B662: https://www.cambridgeshire.gov.uk/residents/travel-roads-and-parking/roads-and-pathways/highway-records/ and https://twitter.com/Cambs_Traffic/status/959021510378868736 (2018) - I can't find any other reference on the internet that it has been downgraded.
