Could someone with local knowledge help determine what type of roadway-waterway intersection this is?

I'm unsure about what type of intersection exists here (bridge, culvert etc.). Could someone help out?

Someone added building with ID 1182903514 after I edited service road with ID 904381754. As far as I can tell, this building is visible exclusively in Bing aerial imagery; it doesn't appear in any other aerial imagery sources. Could someone resolve this?

Does anyone know what type of highway-waterway intersection this is? I can't tell if it's a tunnel=culvert, tunnel=flooded or something else. Thanks!

Could someone with more complete knowledge confirm that intersections between these 2 highways actually exist?

Road 645363873 overlaps a large number of buildings in this region (additionally, several buildings overlap each other). Would another editor be able to resolve this?

Bridge or culvert? Could someone help out? Thank you.

Does anyone know whether this would be a bridge or a culvert?

Bridge or culvert? Anyone know?

This bridge and waterway are misaligned. Could someone with local knowledge please resolve this? Thank you.
