I read on this web site that the bridge has been mention by NASA personnel
go down about half way at the "Another wierd conversation about tracks" heading
NASA scientist Farouk El Baz admitted in a magazine interview that NASA did commit itself to a secretive search for various things on the Moon. 'We're looking for something - something ...' He admitted that 'a huge bridge-like structure in Mare Crisium has been reported ... That is all I can say about it.' When asked if 'that was a bridge - that you've actually found artificial structures or some kind of intelligently placed artifact?' El Baz quickly denied it.
'No. No. I am not admitting such a thing. But when you start to think about it, almost anything is possible. There are almost no limits [to] how you can interpret the many things astronomers have been observing and reporting for several centuries. Now the astronauts are seeing many anomalies close up'.

There is another round arched structure with a square door-like feature in it in one of the craters (the one on the left) too.
The sky has been completely replaced with one colour grey and there are no compression artifacts in it at all. Just make the photo lighter and you will see what I mean.
It's clear that the "bridge" doesn't line up with the craters from photo to photo and so can't be a feature on the surface. It has the appearance of a ghost reflection off the window of some illuminated part of the inside of the cabin. But it is without a doubt not a structure on the surface.
Ok this comes from another Apollo 15 photo, AS 15-87-11701. Top left corner of the photo is loaded with anomolous structures including what looks like a bridge going nowhere. I included the original as well as one I worked on a little.
