Chile's public works ministry (MOP) will spend some 10bn pesos (US$20.8mn) over the next two years to modernize international highway Ruta 60-CH in central region V.
The project involves paving, reinforcing retaining walls and other works, on a stretch between towns Juncal and Portillo, close to the border with Argentina, the regional MOP office said in a release.
The ministry also expects studies for construction of the Chacabuco II tunnel to be completed this year, and aims to begin works in 2012, according to regional MOP director Pedro Sariego.
MOP's highway division will invest some 8.7bn pesos in the region's Los Andes province as well as nearly 3bn pesos in San Felipe province, which includes funds for periodic maintenance, highway improvements and small bridge projects.
The ministry also plans to carry out road improvement works in five other communities in the region and plans to build several small bridges.
