You also might look at the road data in the National Imagery and Mapping Agency's Vector Map Level 0. There's several links and descriptions of the data on this page:

But if you just want to jump to the data, check out:

Data exists at higher resolutions but is more patchy in several locals. For higher res, checkout VMAP1: http://www.mapability.com/index1.html?http&&&www.mapability.com/info/vmap1_intro.html
