+100 to this. I was thinking about this the other day. Google navigation offers this as well. To make it really shine, I think that it would be nice to include the alternate name as well. I am not sure what separation would be best on the screen. For example, Main St / State Hwy 906. In looking at some areas though, this can pose a problem as there are alternate roads listed with the same exact primary street name. I wonder how easy it would be for Waze to run a script at map tile update that deleted multiple of the same name at a road segment? For example Primary: 3rd St, Alternate: 3rd St, Alternate: 3rd St (3rd St / 3rd St/ 3rd St is not good looking)
