The detail on the photo is great, but the perspective is well south of the northwest tower of the bridge, and at the same time well west of the southeast tower. This is either the result of blending adjacent satellite photos taken from significantly oblique angles, or multiple aerial photos, or a single aerial photo from a relatively low altitude, southwest of the bridge. My guess
is that the most detailed section is not satellite. Google says
Similarly, the imagery found in "Satellite" mode is sourced predominantly from DigitalGlobe and MDA Federal.
and Google certainly uses EarthSat images from MDA, but MDA sells both satellite and
aerial products. I notice that Google put "satellite" in quotes...
In the end it doesn't matter, and it may well be all-satellite, but the perspective of the photos causes some interesting effects in the images, such as those "leaning" bridge towers and blank areas beside some structures.
