Tokyo is moving ahead with a long-delayed infrastructure overhaul aimed at restoring open sky to one of the city¡¯s most culturally significant landmarks ¡ª the Nihonbashi bridge.

The capital¡¯s 17th-century bridge, long overshadowed ¡ª literally ¡ª by an elevated expressway, is at the center of a multidecade project to relocate the highway underground in hopes of restoring the scenery around the bridge.

Once complete, the project is expected to reshape a key district of the city¡¯s historic core, with officials promising not just improved traffic flow, but a revived public space.
