I live close to route 20…it is a nice scenic route and was once considered a major interstate across New York State. The road is in good shape but it is not an interstate. There are some four-lane sections as well as Two-lane sections going through small towns with stop lights. That being said, consider your average speed on this road to be 10 to 15 mph slower than an interstate. If you're on a tight schedule I would not take this road otherwise it could be a nice change of pace. Also if you're moving too slow on route 20 you could always hop back on I-90 .
