Google Earth: KML/KMZ files with exits labelled

[Chris]

What I am looking for is the following:

A Google Earth file (KML/KMZ) that has all exits of the Interstate Highway System as a placemark. So you can see in one view what the exit number of a certain freeway exit is. Would be even better with all the freeways. Now I have to check with my Rand McNally atlas or Wikipedia to see which exit number an exit has, but it would be easier if they're displayed in Google Earth...

Has anybody ever found something like this on the net?
