NY 10 from Arietta to Piseco is the most odd road. 🚗

It’s a modern road with well banked curves, smooth surfaces, fairly wide lanes, decent sight distance and tight curves.

It is built to modern engineering standards, bar the curves.

It was built around 1980 from an earlier dirt road, so it uses all the knowledge and standards gained through construction of the interstate highways. Some sections are comfortable to drive at ordinary highway speeds. But other places have incredibly sharp curves, despite the banking.

The reason comes down to a lot of the road runs through forest preserve. Any change to the routing required removal from the extremely limited highway safety land bank in the Adirondack Forest Preserve or a constitutional amendment. So the NYS DOT, at least through the forest preserve continued the original routing as much as possible through the forest preserve while only making relatively minor changes outside of the preserve.
