This road was not what the map (or the local police) promised. It appears as a paved high quality road on my map, it's more like a horse trail through the mountains. Thank god we had a 4X4 or we would have definitely been dead. 6 hours at night on this road from Constanza to San Jose was the best thrill on this island second only to the ladies. I wouldn't recommend this road for anyone who is sane or afraid of heights. The highest point I measured with an old aircraft altimeter was just over 10K Ft. Definitely an E ticket worth riding again, but my Dominican girlfriend is refusing to take the journey again.
P.S. - Bring lots of gas, food, drinks, and anything else you may want, because there is absolutely nothing along the way.
