i dont think u can do that bcos roads already built-in inside the map itself
as our local map (www.malsingmaps.com) .. only map author hold the right to add/delete/update map, but in this case (malsingmap) others can contribute and mappers will update the map.
but i'm not sure google requires our contribution as well to update the their map. They usually buy maps source from local company and put into their map

We cant add anything to the GE's layers. They are done by Google and the collaborative companies. Works are underway (only three countries are finished and uploaded for the roads layer).
But you can add overlay images by the "overlay" tool in GE. You can draw paths if you have the Plus version or can manage with free tools by 3rd parties. And you can post them to this community as an attachment. So, everybody can see your work before Google finishes and updates the database for your area. Your works will be converted to little "i"s after the placemark uploads to the GE server which is done "at least" once a month.
