I remember having reported a similar case before, but the cursor is a railroad bridge even though it is a road bridge.
I've always wondered about that as well. If I remember correctly It's the only bridge in the pakset that has it. It's weird.
There is simply no road sprite in masonry viaducts image.
Edit: I just used my nonexistent graphics skills to fix this. I hope the graphics is acceptable, re-rendering would be better though.

Yes, this looks much better. Thank you.
Thank you - now incorporated.
