Zooming in and clicking into the google maps page for the "subway" allows access to some recent photos. It appears he trestle overhead has been built up into an embankment.
Also this bridge shows up in Bing aerial imagery, so there's also that.
This is actually a common situation on this website. The bridge is open to traffic above, and thus is considered "open to traffic"; despite not being open to traffic below.
In addition to Mr. Conro's accurate statement, I believe both of us can verify that this bridge is not "open to traffic".
I know this area and am fairly certain this is bridge is not at this location.
