Talk:Gyeongbu Expressway

"Second oldest"?
This page currently says it's the second oldest seemingly without a source. On the other hand, Expressways in South Korea says it's the oldest.

I probably won't research this for now, but does anyone know if it's the oldest or not? If not which is the oldest? toobigtokale (talk) 22:37, 14 September 2023 (UTC)
