>>1534801* What's good is integrating carpark (Yaesu Route, Showa-Dori underpass) and railway (Oedo Line at northern Yamate Tunnel) to underground roads. Median carpark access (all around Japan, and eg Civic Boulevard with the main railway corridor underground in Taipei) is nice too.
As a side note, the last remaning Civic Blvd Section 6 east of Songshan Station was finally completed last month.
