Oregon Hiway 42 from Winston to Coos Bay?

Just got off hwy 42 from I5 to 101 in Coos Bay 2 days ago. The road is good surface, 40 ft wide in many places, narrow shouldered, curvy, and winds down through river valleys toward the coast from the Oregon coastal mountain range. All forested and elevation drop is about 700 feet from I5 to 101. We do this highway all the time and it is a good route but curvy. Traffic not bad but watch out for the "chip hauling semi trucks and log trucks. Average rv speed probably about 40-45 in the narrow parts of the route.
