From this Youtube video It sounds like "the Junction" is between St Andrew's and St Mary's parishes, which are both to the north and west of Kingston. So it would seem that the inland route is the suggested one.
From what I can understand on the Toll Authority website, the only toll roads in Jamaica are not where you are going.

It is the clockwise route. There are no tolls on this route.
Condition of parts of this route is very sub standard.
