Chile's public works ministry (MOP) will invest nearly 15bn pesos (US$31.3mn) in two highway projects in north-central region IV's Limarí province, the regional MOP office said in a release.
Local firm Arauco will modernize the 16km San Julián-Las Ramadas de Punitaqui stretch of highway Ruta D 555.
The project involves paving and construction of two bridges, as well as well as 6km of bicycle lanes. Construction will cost more than 7bn pesos and is scheduled to take 540 days.
Compatriot firm Tricam will have 330 days to upgrade the 14km Soruco-Combarbalá stretch of Ruta D 605, which will cost more than 6bn pesos.
Work involves paving, building the Lanas and Pama bridges, as well as pedestrian crossings and bus stops along the route.
Construction on both projects is expected to begin within the next few weeks, the release said.
