Sorry I dont have that info, but did want to mention that the south end of the road will b a place to avoid this weekend May 22 and 23rd. There is a major car race in the vicinity both days
Not sure about the "York Pond Rd" section, but I know the section to Rte 26 by the NHF&G Umbagog boat launch is passable. Gate down by Seven Islands bridge in 13 Mile Woods is closed.
