Parts of the motorway, as well as a local road, have been able to be restored and are open to traffic, but there is still ongoing work to be able to reopen the adjacent commercial area.
The Swedish Transport Administration has so far covered the costs, but now requires Stenungsund Municipality, which annually turns over around 2.2 billion kronor, to pay the price tag of over half a billion kronor.
The demand is based on the Accident Investigation Authority's report, which, among other things, points to the municipality's inadequate consideration of prevailing soil conditions when permitting earthworks - which could have partly caused the landslide.
If the costs fall on the municipality, it will mean both debt and halted investments, according to Olof Lundberg (S), leading municipal commissioner for Stenungsund.
Then it will be quite tough ahead, he says to the newspaper.
