Since you now mention you are going to San Francisco, may I suggest an alternative route?
Just be sure you have plenty of fuel before leaving I-10! There are no services along this route, but it completly avoids LA and all that traffic.
Also once it reaches I-15 by Hesperia, do NOT take 18 across, as there is ongoing construction by Palmdale.
At Az exit 45, on I-10, (Vicksburg Road), go north into Vicksburg, Az to Hwy 72 .. follow 72 west to Parker, Ca, where you will find Ca Rt 62 west, to Rt 247, by Yucca Valley, then north on Rt 247 to Victorville and I-15. There are several ways to get on over onto Hwy 395 north, (choose your own local route). Then Hwy 395 north to Hwy 58 to beyond Barkersfield to I-5.
That route is 2813 miles, and avoids Los Angeles all together ... and a pretty run in the daytime ..... see if you can spot Rice AFB out there!
Where are you delivering in the Bay area?
