I added layer=0 to the lower way, which helped, but 
http://www.openstreetmap.org/?lat=39.3981428965518&lon=-77.4003311023415&zoom=13&layers=0BF 
is not quite right; I think this is the lanes=2 tag spreading the I-70 
out, which may be a bug? I can't see anything else wrong with it, and 
it's OK at zoom 14+

This is my PC's T at H render, BTW.
