Those are great photos of the Airline..... That ride was to a bog/swamp/heron rookery just before the trail turns to pavement just on the eastern outskirts of Willi, 18 miles. It is about 21 miles to the Wiili River crossing. The history of the railroads and rivers and manufacturing in this area is very interesting. If you enjoy the Airline you should check out the southern section south of Willi, the Hop River trail connects to it the same area which heads to the northwest/Hartford. These are both about 18 miles with short 3-4.5 mile spur trails. All gravel. All the info on these is on trailink.org/RailstoTrails along with all other railtrails. Sign up for free, great info.

44 miles is not that much for me, I'm a lifelong cyclist in my mid 60's along with 25 years of mountain biking, I'm retired so I get to do more now. I did an 80 and 100 mile rides last year on the Airline, all gravel except for a few miles in Willi, I really like the long steady rides, I did 50 out there today..... If you are north of Boston you should check out the Rockingham Rail Trail near Manchester NH..... The Northern Rail Trail from West Lebanon to Boscawen is the best RT I've done in New England, 60 miles one way and in amazing condition.

I wouldn't recommend riding east of Pomfret Station, you could do maybe another mile, not improved but rideable. After that is gets nasty, wet and muddy, even I won't ride it and I ride anything for the most part, LOL. it should get finished in a year or two.
