drive from north america to south america

In 1957, writer George Stewart set out to drive as far north and south as possible from the continental US. He made it as far as Circle, Alaska and Santa Isidro, Costa Rica. He wrote about his journeys in NA 1. I would like to drive from Prudhoe Bay to Tierra del Fuego. I don’t know if there are connecting roads between Panama and Columbia, but I want to give it a try. I would like to write a book about the journey and see it published.
