The Consejo Nacional de Vialidad, the road agency, said that it is beginning major repairs on the Interamericana highway in the southern part of the country.
The highway was damaged by Hurricane Tomas in 2010 and subsequent storms. Work in the 40-kilometer (25-mile) stretch is expected to cost 4.5 billion colons or about $9 million. The work includes putting in a cement base.
The Interamericana job will join with a rebuilt road from Rincón de Osa to Puerta Jiménez on the Osa Peninsula. That was a $29 million project of 32 kilometers or about 20 miles.
The work is part of a package to improve transport in the southern part of the country.
