A year or more for a road closure

Since the floods in February,the road from Bath to Keynsham has been shut due to a road slippage collapse.
The local media have said it may be open again in December.
What are they doing about it to fix the problem?
Another road that was shut but is now half open is the Hinton Charterhouse to Bath road,for a landslide of mud.
No rush on that one too.
When Japan had an earthquake,the road was rebuilt in one week.
Any busineses in the two above roads must be bankrupt by now.
