It looks like something in Google's software is causing the signs to be blurred out. Maybe it's identifying them as faces.
Anyhow, in Street View you'll see a circular sign with a pinkish blur, and usually a white rectangular sign below the circular one which lists the route number.
The stops are also identified by icons on Map View if you zoom in far enough.
They seem to come & go depending on the zoom level, so zoom in at least 1 level past where they 1st appear, and then zoom out & in a couple of times.
