There are various service roads to garages and courtards to east of Skipps Meadow road. These need a survey. Again, it's on my list to do, unless anyone gets there first.

What is the evidence for this having been downgraded? It's still showing as B662 on OS and Google Maps. 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.

CR-24 takes the newer road to the north - I drove this about a fortnight ago. However, I'm not sure how the tie in to the east works so some local knowledge is needed.

I believe there is a new roundabout on the A151 south of Peppermint Junction to open up land for development, however, I've not personally surveyed this.

There are collector/distributor lanes here, I added an approximation of them after a site visit last year; however, these have been removed by other contributors. Having driven through recently, I can confirm they are definitely there, but cannot remember exact configuration to re-add them. Someone with local knowledge will need to fix.
