One reason roadways become rough is because overweight trucks can damage the pavement.
The highway authorities said work has started on a new and modern weigh station on the Autopista Florencio del Castillo, between San José and Cartago at Ochomogo.
In addition the agency, the Consejo Nacional de Vialidad, said it expected to award bids for the remodeling of a station in Esparza.
That location is on the Interamericana.
Both jobs are expected to be finished by the middle of next year. The investment is 660 million colons or about $1.2 million.
According to the Consejo, both stations will be fairly high tech to measure precisely trucks and their loads.
There is an additional weigh station in service now at Búfalo on Ruta 31, the highway to Limón. That route is traveled heavily by trucks going to and coming from the Caribbean docks.
