I think that Rt 47 is closed from Rt 28 to Frost Valley. From what I understand that the road is washed out just below the lake. Someone told me that they are not going to fix it until next year. Real issue for people wanting to access Slide Mtn from Rt 47. You can get there from the Neversink, but it will add some miles.
They are now working on Rt 23 from Windham to Prattsville. Hopefully, it will be open soon.
Not sure about Rt 42 at the deep notch.
