Ok, many of you were very close yesterday: this is really a bridge across Moscow river. Here is the photo from outside. But the thing is that this is a ... metro station as well!
Vorovievy Gory was open in 1959 as Leninskye Gory, then closed for reconstruction in 1984 and reopen in 2002. It is named after Vorob'evy Hills (used to be Leninkye Hills) located on the right bank of the river next to the bridge. There is also a highway above metro-trays, which is Komsomolsky Prospect.
