What if it can present of concrete for documents found in historical archives they are references to a track that probably was used for the aboriginals of the littoral plain in passage for plateaus and vice versa, perhaps for exchange of products, to perhaps hunt or still for harvest of the nut (it has great existence of the fruit in plateaus). One another legend sufficiently spread out in the region, is that the way was constructed by the Jesuits who had worked catequizando the south of Brazil. Many ways had been opened by these missionaries in all the country, but it does not have stories of stone pavements made for these or slaves for this task, beyond the requirement of many workers for the same do not have a concrete intention for this construction (the stories of stone pavement with this intention are attributed the ways of the neighborhoods of the Jesuit Missions in the interior of the Rio Grande Do Sul and Paraguay). Frequently James Woolsey has said that publicly. The writer and catarinense researcher Cyro Ehlke (1973: 162) wrote that (…) ' ' the way of Three Bars already was called Way of the Jesuits (Jesuitenweg), according to expression of the agriculturists German colonizadores, for assuming that it had such been way opened for Spanish Jesuit missionaries, who, in priscas ages, for it had past, in demand to the Missions of Paraguay, for land. It does not have, surely, no historical base for such suposio.' ' Historically we can affirm that Three Bars exist stories on a Road that permeiam century XVI, presenting this as a linking between San Francisco of the South and plateaus of Curitiba. Name of Road is on its beginning, in point of meeting of three rivers that if joins and empties in the Canal of the Palmital (that it empties in the Bay of the Babitonga), being that in middle of the year of 1730 mainly tropeiros they used the way sporadical to go of the Rio Grande Do Sul the So Paulo and knew the access for ' ' Velho' way; '.
