Dear Aurimas,
I checked the bing photos. I still think it is a bridge with bearings axially parallel to the street. And I think it it is more helpful to map it like a bridge, because you discover already in zoom 15, how you going to drive. 
I have looked at this point, because I haved planed a track to Trakai by bike and I discovered that I coundn't cross here.
Greetings from Germany,
Jens
