Is this road open and without major issues now ? I recall the locals blocked it a while back as a protests... Also sometime there used to landslides and drop trees that blocked it occasionally, so I wondered if anyone used it recently....
Like Hillbilly said unless you have a jeep dont do it to many pot holes, I have done it several times in last few months but always in the isuzu Rodeo never in a small car. I would second HB and say go thru Jamao norte.
