The Consejo Nacional de Vialidad said it reestablished the section of Ruta 34 after work that took nearly all of Tuesday. The agency said 3,000 cubic meters of dirt and rock poured down on the highway after heavy rains in the area.
That is nearly 4,000 cubic yards or a pile 40 yards long, 10 yards wide and 10 yards high.
Initially only about a quarter of that amount fell, but slides continued as workmen tried to clear the road, the agency said. The slope near the road was considered very unstable when soaked. Officials will continue to monitor the section.
The section is just 2,000 feet south of the Tårcoles cemetery. The highway is in heavy use by trucks and other vehicles going north or south that do not want to pass through San José on the Interamericana highway, Ruta 1.
