In that case don't change a thing until you have personally verified the layout of the road in question. Aerials can be out of date, construction can totally change the layout of an intersection or interchange and until the aerials are updated the road will fail to match the GPS tracks. Now GPS tracks are not the most up to date either anymore.
Thus leaving the option of going out and driving the road.
Now I go and look at the link.
Both the roads were last edited in April, that is more than long enough for the GPS tracks to adjust to match a new route, as the GPS tracks follow the drawn roads exactly (except for the normal small percentage of bad track off-shoots). I definitely think the images are out of date.
