I need a US highway shape-file for a current project. Does anybody have a good source for US interstate or highway data? Preferably free

Got lots of download time?

If you need alot of time to download add it into your price. And you will need to do a quarry to separate the road data.

You can try the downloads from CloudMade made from OpenStreetMap data:

It's got way more than just highway data though.

I'm fond of the Natioanal Transportation Atlas Database (NTAD), issued annually.

Thanks all, I found what I was looking for on the National Atlas site. I had to actually read the metadata to determine the projection and coordinate system then MANUALLY set it in MAPub... it's like the dark ages!

I've been working with the National Highway Planning Network data. It seems to line up with all my other stuff really well.

I'd love to hear about some of the pros and cons of the aforementioned data sets from someone more experienced than me.

For me it all depends on scale. I don't like the census data or from what I read about this data b/c it is produced by digitizing 1:100000 scale maps. Too coarse for me, but the scales that I work in are mostly local and occasionally regional. I like to use 1:24000 (25000) data and dumb/simplify it down in Illy. That way I have simplified data with beautiful curves that is still georeferenced well.
my two cents,

It varies. Current (2009) TIGER data in urban areas is built at 1:10,000 and has some lovely curves to it. Surprise!
OTOH, there's still some of the 1:100,000 data out in rural areas.
