The hole appears to be between the Upper Grosvenor Road / Dunstan Road / Grosvenor Bridge crossroads and the Upper Grosvenor Road / Queens Road intersection.
Thus, 281 buses are running Tesco's > St John's Road > Cross Keys > Powder Mill Lane > Yew Tree Lane / High Brooms Road crossroads, then normal route. Reverse as outwards.

However, from the Arriva website, dated 8 May:
Due to a collapsed sewer in Upper Grosvenor Road at Tunbridge Wells, Service 281 buses are unable to take their normal route between the town centre and High Brooms.
A temporary diversion via St. John's Road in both directions will be replaced from Saturday, 9th May, by a circular route running from the town centre via St. John's Road to Powder Mill Lane and then direct to Barnetts Wood terminus at High Brooms.
Buses will then return towards the town and Rusthall via the normal 281 route to High Brooms Rail Station but will then turn left under the railway bridge into Sandhurst Road and then via Ferndale, following the Service 277 route to Tunbridge Wells War Memorial.
~~~
Residents of Ferndale area unexpectedly now get a much enhanced service!

Until the road re-opens it will not be possible for us to serve Upper Grosvenor Road.
