Impress is not the main reason I'm sure, the road was undooable and now its possible to use, so necessity was a large % of the reason.
To bad we couldn't get some of them staying at Blue Reef and get the other half of the road fixed.
You still have to use the beach to pass between Portifino and Journeys End.
