Wash DC to San Jose (fastest route?)

[mk1]

hi, i'm about to drive to from Washington DC to San Jose (about May 1st).

when set to "fastest route", my GPS is taking me through RT-70 then down to RT-40 (towards the South....to Southern CA then up to Northern CA).

MAPQUEST: is sending me on RT-70 then RT-80.

almost same estimated miles and time.

which is faster in terms of traffic wise?

how about any chance of snow this time of year in Utah and such?

thanks.

I doubt you'll find any snow. MS Streets and Trips suggests the fastest route is I-270 to I-70 to I-76 to I-80 to San Jose. Driving time is about 41 hours at standard speeds. Using I-70 to Denver and going north to I-80 from there adds about 2 hours driving time, supposedly.
