Transportation strikes (bloqueos) are a common occurrence in Bolivia, so try to keep tuned to local news. Strikes often affect local taxis as well as long-distance buses; airlines are generally unaffected. Do not try to go around or through blockades (usually of stones, burning tires, or lumber). Strikers may throw rocks at your vehicle if you try to pass the blockade. Violence has sometimes been reported. Many strikes only last a day or two.
There is a government website with a live map showing which roads are closed or affected by landslides .
