Highway officials plan to make the route from Puerto Jiménez to Carate in the Osa peninsula an all-weather road. This is about 43 kilometers, and the job will take five of those metal bailey bridges.
The bridges are going in at the ríos Sombrerito and Piro and the Carbonera, Bijagual and Camañín waterways. The work will provide access to a small airfield at Carate, said the Consejo Nacional de Vialidad.
The job is estimated to be about $2.5 million, which includes improvement and gravel for the entire stretch, said officials.
The work is expected to begin after approval comes from the Contraloría General de la República and environmental authorities. That is estimated to take about three months. The job, itself, is expected to last four months. Some of the work will be to install concrete footings for the bridges as well as retaining walls, according to the plans.
The improved road is expected to provide better access to the Parque Nacional Corcovado.
Lack of bridges closed the route during times of high water.
