That road is probably not fully completed I have taken part of that road and it isnt the best. Why not take the main HWY to either Pierda blanca and then take 17 into Cotui (hope you have a jeep) or take the main hwy to ext for Sanfrancisco de macoris then follow signs thru to Fantino then onto Cotui the roads are nice that way!!! Either way let me know how it goes
