We've got our trip planned out so that DW gets off work and we arrive in Monterey on a particular date (for the annual Historic car races) and can't afford to add much time. We were on 395 last year and it is a really nice hwy but it's too far east. I don't think 101 would work for us either, although I would love to take that route. So it sound like only some sections have been re-surfaced.
I really like the run up Grants Pass on the north side and would hate to have to miss that. Yes, parts of I-5 can be barren but at least not as bad as from SF to LA. Forest fires could potentially affect things too.
We're doing a leg out of Seaside in the northwest corner of Or. to a CG in Redding and that is a long enough drive as it is. What about hwy 66 out of Ashland to Klamath Falls and down 97 back to I-5 at Weed or perhaps going a bit farther east on 39/139 and then 299 to Redding? The hwy 66 on our map shows it as a secondary hwy and may not be a good drive tho.? We were on 299 last summer and it's definitely a nice drive.
I would assume there is a website(s) that tells you what the I-5 condition is like and where it's bad? We've got a Garmin RV 760LMT GPS now and it would be nice to program in the sections of road that are bad. The 55 max speed limit for towing is a bummer, esp. on nice straight sections of hwy. I never go above 65 but 55 seems like you're standing still in comparison. Are we going to get pulled over for doing say 60 mph?
I've read before that the reason the concrete sections of I-5 have taken such a beating is that the suspension on semi trucks and tractor trailers have a harmonic frequency that coincides with the spacing of joints and the trucks literally pound the concrete into the ground at the joints.
