2 TM users have travels so far.
The systems seem to need overhaul before being ready for a peer-review according to the note on the overview list.

According to https://wiki.aaroads.com/wiki/A8_(Kenya) the routes were renumbered in 2016. https://igrtc.go.ke/views/img/resource/IGRTC/Legal%20Notice%20No.%202%20of%202016-%20roads%20and%20libraries%20(1).pdf seems to list the new routes.

I don't have anything to add here, but will be (briefly) on the ground in June, travelling from Nairobi to Tanzania, so can see if there's anything from a signage perspective. GSVing doesn't show a ton.
