New Border Road At Risk

A large proportion of the ¢ 20,000 million that the country has invested in building the border road with Nicaragua, could be lost during the next rainy season.

This is a warning from the engineers of the National Laboratory of Materials and Structural Models (LANAMME) at the University of Costa Rica. They inspected at the beginning of this month, 97 of the 160 kilometers of this road.

In their report, the experts say that lack of adequate drainage, and the instability of cut and fill material that were performed on Route 1856 could become a headache with the arrival of the rains.

According to the report, the LANAMME, the consequences of this collapse can result in “a substantial loss on investment.”

During the tour, between Costa Rica Delta and the River Pocosol, LANAMME mission found that the high slopes and irregular layout of the road was prepared based on the experience of machine operators, without topographical and geotechnical information .

Government authorities have not wanted to speak on the subject of the study, say that they do not know still.

The aim of LANAMME was technically assess the configuration, quality and functionality of the works carried out on the trail border.

Another of their findings was the use of inappropriate materials to stabilize the surfaces of the ring and its transport over long distances.

Inspectors found that, in some places, They placed some large river stones as surface course.

In other places put very sandy materials that are easily displaced by traffic, wind or water.

The Government announced the construction of the trail as an alternative to the San Juan River for the transit of people and goods at the border with Nicaragua.

Its construction was carried out under emergency decree number 36440, signed by President Laura Chinchilla.

The LANAMME report, warns that despite the state of emergency, the design problems could be solved in a short time, using georeferencing techniques and software engineering to guide the work.

One of the threats confronting the trail border is the lack of adequate drainage to channel the flow of rain that will fall during the coming months.

Engineers found that in the construction of the route, placed containers (of which are used for transporting goods) as structures for draining river.

With the fall of material, these containers are already deformed and at risk of collapse. This problem is shown by the photographs included in the report.
