I would normally take rt 9 so that should answer your question it takes nearly the same time IF you have no traffic and you like windy roads while maintaining highway speeds.... so in short its not a prime towing road

I think route 3 would have worse traffic problems with the construction on that side but as long as your not traveling at 5pm in that area it is probably OK. If you do take route 3 ( which h is what I would do) DO NOT STAY IN THE LEFT LANES AS YOU NEAR THE TOLL. It has a massive dip (almost a hole) that you really want to avoid! Good luck and have fun.
