On visits to Esher on Wednesday and Thursday this week (6th, 7th December
2017) I noticed that the TfL K3 bus (Esher, Claygate, Kingston, Roehampton
ASDA) appeared to be on Diversion, going down the old Portsmouth Rd and
missing out Claygate.

I tried to check this on the TfL website but not a trace. Nor could Google
find anything recent.

Where is or should it have been and is there any history?
