EeeeEvil DeeEeEemon Google Maps shows 3 different routes which are about 45 minutes from town to town.
One of those routes, the back road way used to be an unpaved back road, but might be all paved by these days. Looks like it is.
To me looks like you could back road it over to NJ 23 then a short piece of I-287 North so to me it looks like you might only hit a small section of traffic on 23.
I would try it sometime during the times you project or even just click on the map at those times and you might get a traffic estimate.
