The Interamericana Norte, Ruta 1, is open to all traffic now at Kilometer 77 at Cerro Cambronero, but there are workmen in the area, so motorists are being asked to be cautious, the highway agency said.
This is the location of another slide and washout caused by excess water. The highway connected the Central Valley with the Pacific coast.
The Consejo Nacional de Vialidad has been working at the site since problems developed Saturday. The road was closed to all traffic for a time and then opened to just light traffic through Tuesday afternoon.
