The toll road essentially goes from Ocho Rios to Kingston.
We averaged about 3½ hours. Going to Kingston from Negril was under 3½ hours and going back to Negril was just under 4 hours.
This was without speeding...and for those that know me...it's true, I really didn't speed..lol.
JD...funny you mention that...because it can be a hilly drive like the Mandeville/Spur Tree road...they've built escape lanes for cars with brake problems etc on this new road.
