Hi Everyone,
There had been a post a while back about a route to LA known primarily to truck drivers which cut down on travel time considerably. I can't seem to locate it, any information on the quickest route would be appreciated. Thank you!Kayla

...traffic on the I-15. You can take the 58 in Barstow to the 14 to the 405. Or you can take the I-15 to Victorville, then take the 18/138/14 to the 405.
When you get to the Slauson cutoff, get out of your car, cut off your Slauson, get back in your car.

Take 15 to Victorville
Turn off for 18west to Lancaster/Palmdale
Take 5 /405 south into LA
It's the old highway which runs north of the mountains
It's one lane each direction no shoulders mostly desert
If you are comfortable with desert highways you'll be fine
Just remember to never overcorrect if your tires hit sand so you don't roll
Will knock a considerable amount of time off the trip in high traffic /rush hour times
Best ran at night imho there's barely any other traffic.
I've used this route for years
I used to own a trucking company
I am grateful for everyone's input, thank you. A special thanks to Kitty...that was exactly the info I had been searching for!

I had to drive that route every 3-6 weeks for 3 years to get Orthodontics. The single lane part is 45min - 60 min? So it's not like all of the trip. I drive to Valencia, one mandatory gas stop, time is right at 4 hours if you're not traveling at an insane time (like Sunday afternoon 
Ortho was free from family hence the many trips
Check to make sure some of these freeways being suggested aren't closed due to fire. I had to delay a Vegas trip once due to freeway closure when most of Socal was burning.

There's another "shortcut" (actually 30 miles longer) available for the section of I-15 between Primm and Barstow if that gets backed up. It's not suitable for trucks but it's fine for passenger vehicles, pickups and SUVs. Again, it's also desert highways to be prepared for some dips and bumps, as well as the advice if your tires hit sand. Also, keep in mind it's a bit off the beaten path so make sure you're topped off with gas, water and munchies before you leave Primm:
Follow I-15 S to Nipton Rd in San Bernardino County. Take exit 286 from I-15 S
9 min (9.8 mi)
Get on I-40 W from Morning Star Mine Rd, Kelso Cima Rd and Kelbaker Rd
1 h 5 min (63.3 mi)
Follow I-40 W to Barstow Rd in Barstow.
Hope that helps some one some day...
