Fairly unlikely that such a data exists(the most likely sources are the
paid ones available for GPS units like Teleatlas or Google who may or
may not sell licenses). Some of this exists in openstreetmap but it is
by no means comprehensive and quality probably varies by location.

You may also find a mix of data from States, Counties and Cities but
that is still somewhat rare.

Someday, with 'your' help OpenStreeMap will be great for this...

Thanks,
