Yeah, looking at maps of that area it does seem a bit confusing, considering all three roads at that junction are labeled "Pacheco Pass Hwy".

Oh, and another thing that will mark you pretty clearly as non-Californian: over here everyone calls the controlled-access roads "freeways", not "highways". It's something I still haven't gotten used to.

On the way back, it'll be much less confusing if you go 80 to 580 on down; the interstates tend to be signed a little better than the random state roads, I think.
