I've found New York State figures.[1] But they don't have a breakdown by fatal/nonfatal. Like the UK data, they show much lower accident rates on divided, limited access highways.
California has a fatality rate of 0.94 per 100 million miles traveled.[2] That's lower than the US average. But it's not broken down by freeway/non freeway. (You can request a login to query the database directly and download data, and it might be possible to compute freeway accident rates.)
