Suggested correction: This might be correct, but it depends on the sun's position. If the sun is to the far left of the shot, the gap in the shadow would appear somewhere far to the right of where the actual gap is.
Nice try. Look at the shadows of the bridge trestles and those on the small brown building to the right of the photo. The sun is to the left of the bridge, and the shadow is exactly what you would expect to see if the bridge was complete - which it was, by the way. The "gap" is CGI.
