I hope this is an OK question to ask here. Since I got my Brompton folding bike a few months ago, I commute to work and have ridden all over New York City, so I'm fine with dealing with all sorts of city traffic. Now I'm contemplate this route in the country, and I think it might be a different ball game:

I'm mostly concerned about the part along 9W, which is four lanes becoming two. It looks like it moves pretty fast, and I'm told it's busy, as it's one of the major routes through Ulster County. And it looks like there's no shoulder to speak of. There's also rather a hill after the bridge, and I only have a three speed, but as it's on a bike path, so I think I can manage it one way or another.

New York City traffic is a lot of things, but it generally isn't fast, and it's usually possible to duck out of a dicey situation. Once I'm on this road, I'm stuck. I gather this sort of ride would be the norm for many on this forum, but for me it's new and different.

So, should this relative newbie urban biker try this? And tips if I do try it? Thanks for any input.
