The Dominican Republic's public works ministry has shut down a section of the El Rio-Jarabacoa highway to begin reconstruction on the fourth stretch of the two-lane, 24km highway.
The ministry included the US$71mn project in its 2011 budget, state news service Antena reported. Work began in November and is scheduled to be completed in 11 months.
Brazilian firm Odebrecht is carrying out the work, which includes building and paving the highway as well as building retaining walls and complementary works.
Odebrecht signed a contract to complete the repairs last August, following a presidential resolution declaring construction of the highway urgent. RV Consultores Internacionales (Coinsa) is supervising the project.
