The Dominican Republic is classified as a middle-income country by the World Bank. In the last 10 years the government of the Dominican Republic has put increased effort in renovating and improving the nationwide road infrastructure to improve connections of the interior of the country to Santo Domingo. This has successfully improved the quality of the main eight highways of the Dominican Republic. Expansion, widening, tunnels, and elevated viaduct have all been methods used by the Dominican authorities to increase the efficiency of the main arteries of the country. DR-1 connects Santo Domingo to the fertile Cibao region, Dominican Republic's second most populated city Santiago de los Caballeros and ends in the Dominico-Haitian border close to Monte Cristi. DR-2 gives Santo Domingo a direct link to the mid-size cities located in the southwestern region of the country and a second connection with Haiti. DR-3 provides Santo Domingo with a direct connection to the important cities of the east and to the main tourist towns of the republic. The other numbered highways provide alternative routes(DR-8, DR-4, DR-6), or work as an auxiliary route(DR-5) from the main routes to connect smaller sized cities to the main highway grid. The following is a table of the main highways of the republic.
Like any developing nation, the Dominican Republic suffers from a lack of good paved routes to connect smaller towns and less populated areas. Some of them are in bad condition or are completely unpaved.
