Hi Judy. I have never driven 299 west out of Redding (only 299 east out of Redding), but keep in mind that Redding is the northern most large city in California's Central Valley. Just to the north is mighty Mt. Shasta volcano (summit is 14,000 feet, although Interstate 5 just skirts the shoulder of the mountain), both to the east and to the west of Redding is mountainous.
Looking at Google Maps, satellite view, although I have never driven it, both 299 and 3 to the west of Redding look a bit dicey for larger vehicles (one can even click down to the actual road, and click along the road to see what it is like - actual photos of the road).
Likely truck traffic on 299 will pretty much be over as soon as Interstate 5 re-opens, so if you have a month or so you should be good.
But stay aware. Keep in mind that 2018 has been the worst wildfire season on record here in California, and with no rain in sight (first sprinkles may - or may not - come by the end of October) it can get worse before it gets better.
Generally,
October is the worst month for wildfire here in Northern California - the reason for this is because by October we have not had not a drop of rain since April or May, summer temps here are scorching (100+ degrees for weeks and months on end), putting vegetation at "maximum dry" by October and then - also in October - the annual fall winds begin to blow. If a fire starts before the first rain, coupled with fierce autumn winds - fire can spread very rapidly.
Until it rains, all bets are off.
I was astonished by the video showing burned-out 18-wheelers on Interstate 5. Traffic was backed up (vehicles were stopped, bumper-to-bumper, unable to move), the fire came, and truckers abandoned their rigs to run for their lives.
