Also, if you make it all the way to Pine Mountain Ridge Road (and actually decide to climb it), make sure you have extra water and some tough tires (or a mountain/cross bike). I’ll let you know next time I am riding in the area.

One quick caveat – I have only done 33 on weekends, so I don’t know how weekdays are. With that said, the traffic along 33 I found to be fine. Up to Rose Valley, there is a decent amount of traffic. However, despite a lack of shoulders in most places, the sight-lines are good in most places so drivers will see you well in advance. Additionally, traffic is still light enough that overtaking traffic will usually move well over into the other lane while passing you. Traffic along 33 beyond Rose Valley gets even lighter – it can be 5+ minutes between car sightings at times for that section. 33 is also a fairly popular motorcycling route, so you will occasionally encounter one of them pushing their speed, but they will also generally give you a lot of room. The only sketchy section would be the few tunnels you pass through. While short, drivers will be going in somewhat blind, so a rear light and picking up your pace would be recommended. Basically, coming from even more car-centric Los Angeles, I found 33 rather pleasant with respect to traffic.
