That makes sense. I have been looking to correct areas where I created a short segment of primary roadway that doesn't provide a meaningful long-distance connection after reading the OSM wiki more. I assume I made this a primary road because it still has the designation of Route 100, which is considered a major state highway. Strangely enough, I have been to that area and there is no signage to indicate Graphite Mine Road is a bypass of Eagle, even though that was the only reason why Graphite Mine Road was built. It would make more sense to me if the PA 100 designation was moved onto the bypass.
