The national road agency says that the gravel road from Playa Naranjo to Paquera on the Nicoya peninsula will be asphalted.
The agency also said that a new contract has been issued to the Grecia construction firm Grupo Albosa for maintenance on the 26-kilometer (about 16-mile) stretch.
The job includes putting down 11 kilometers of gravel, which will become a base for the future asphalt job.
The asphalt job depends on legislative approval of a loan from the Banco Interamericano de Desarrollo. The project also includes drainage, inprovement of bridges and channeling of water, said the Consejo Nacional de Vialidad.
This roadway is a key link but it is usually in disrepair. Sometimes, mainly in wet weather, it cannot be traversed.
