I used to know someone whose job was to get all the permits, find a route, etc. for a company that was involved in moving loads that were consider too wide or heavy for the normal moving companies. I’m fairly certain the company responsible for moving this house would be responsible for any damages that would have occured to the house. They probably have insurance for accidents anyway.
As for the damage to the highway, um, well I’d say the county where this happened would pay to fix the bridge but they might sue for damages if the moving company didn’t follow weight limits.
