This is the Braulio Carrillo highway that is a key route to the east and carried a lot of truck traffic. Now vehicles will have to travel on an alternate route through Turrialba.
Spokespersons for the Ministerio de Obras Públicas y Transportes warn that the time needed might be made longer by bad weather. The location is 10 kilometers (six miles) north of the Zurquí tunnel, a spot that is not considered prone to slides even though the soil rises up nearly vertically.
Officials said that the dirt and rock dumped on the two-lane road was at least eight meters high, some 26 feet, and 100 meters long, about 330 feet.
Motorists also can take a route through Vara Blanca to San Miguel de Sarapiquí and La Virgen. That is a hilly route not suitable for large trucks.
Ruta 32 frequently is closed by slides during the rainy season.
Officials have admitted that the entire route through the mountains needs to be rebuilt.
