This was a 3.5-mile four-lane elevated freeway in the middle of a divided surface road with a stream underneath. The west end of the main portion (pictured above) was here and the east end was at the still-extant Naebu Expressway (the stubs can still be seen). A branch (included in the length) began at the west end and ran south to the 1st Namsan Tunnel (남산1호터널), which leads to the north end of the Gyeongbu Expressway. Thus it was part of a connected system (though not necessarily the best through route to anywhere).

Not that there's anything wrong with a declining birth rate.

That expressway was demolished at the same time the Seoul Ring Road (Expressway 100) opened to traffic.

Korean cities are dense, but they tend to have much wider roads than in Japan. Many expressways feature eight lanes around Seoul.
