I'm planning on going from NY10 to MA10 pretty much on 23. I do see I can avoid the four lane, I believe it probably is limited access on the west side of the Hudson to NY145 by taking Main St(I think 23A) instead, which is what I'm planning on doing. I think the rest of the 2100+ mile trip is set so I'm avoiding limited access roads...at least I hope. The trip I was on last month was pure he.. thanks to constantly running into limited access crap. I don't mind the traffic, deal with it all the time, but I hate see the signs that say "Bicycles prohibited".
