This Kotesashi Rikkyo crosses over the Seibu Ikebukuro Line, right next to Kotesashi Station. It's a very long bridge and some ot the space underneath is used as a bicycle parking space.
There are also stairs that lead up to the bridge above, which has a sidewalk for pedestrians, too. You wouldn't be able to tell from above but the bridge is very green!
