The highway starts with the Autopista Las Américas DR-3 (30 km east of Santo Domingo) and ends at the intersection Cruce Rincón de Molinillos, Samaná Province.

There are three different toll booths: the first one 300 metres after the southern start of the highway; the second one at km marker 16; and the third one was built in La Reforma, right before Samaná and the Cruce Rincón de Molinillos intersection.

The actual construction of the rural highway started in the 2005 by the Secretary of Public Works and Communication (Secretaria de Publicas y Comunicación, SEOPC).

It passes the city of Monte Plata, Bayaguana and the Los Haitises National Park and 12 bridges had to be built to cross difficult terrain and rivers.

The new two lane toll based highway is expected to convert Samaná to another thriving tourist hub and it makes the Los Haitises National Park much more accessible to the general public.
