View looking south at the interior of the tunnel that helps support the "Nysa Bridge." This tunnel was originally 300 ft. in length and help divert the floodwaters of the Cakircak stream. The bright sunny area is where the superstructure has collapsed, but the tunnel continues beyond it.
This structure is called a "Bridge" because of the way it was constructed. To this observer, it looks like it formed part of the structure that supported some of the seating of the stadium—some of which still exists but much of which has collapsed into the stream.
