Recta de Azua
The most famous stretch of straight highway in the country, located at the entrance to the town of Azua. It is not the longest (about 9 or 10 km) but it is the most iconic (it is a notorious section of the Sanchez Highway known for speeding).
I tested a Chevrolet Spark on the recta de Azua and hit 60.
