In sucre now. It seems that the buses are taking alternate routes around the roadblocks.'it takes longer but you eventually get to your destination. Also night buses seem to have an advantage on that the roadblocks are not 24 hours per day. Sucre itself is operating fine.
We just arrived in Sucre this morning at around 07:15 via a night bus from Uyuni. Everything seems fine in Sucre, we've just been walking around the city this morning. Seems a nice place to explore
