Hi Jennifer
Another option could be OpenStretMap, http://www.openstreetmap.org/
We have long intended to jump start in the US by uploading TIGER into
the OSM database. Once in OSM, the data is ready to be improved apon ..
creation of custom basemaps is what it's all about.
Many states maintain base maps which are better than TIGER. I think it
would be better to do this on a state-by-state basis. Here in Minnesota
you can download the data from MNDOT.
For the OP: I'm not sure if Caltrans is the CA equivalent of MNDOT, but
that's where I'd start.
Good luck,
Reid
