Ventilating System of Shutoko Wangan Line Tamagawa Tunnel

Tamagawa tunnel is the underwater tunnel fron the south edge of Haneda airport to Ukishima junction. It has ventilating system at both end. This picture shows one in the Haneda airport.

 

I think the color of the sky was lighter than this picture. Since the building was shining with sunlight, exposure was reduced and the other things got dark.
