I've been over that route in the summer and was quite happy to get to Gold 
Beach. I did stop to hike up Mount Bolivar.

It's deceptive in that the road is paved and well maintained along the 
Rogue River. Then you get to the launch point for the rafters. The road 
crosses the river and is gravel with unmarked junctions, swinging well 
away from the river until you get near Gold Beach. Given that it was 
winter, turning around at the raft launch area would have been a good 
idea.

Different formats are used for vector data. Navteq used the Z axis so if a 
segment broke on an overpass it could have the same to/from X and Y 
coordinates as the street below but a different Z. Some of our clients 
sourced their data from Navteq but our code didn't handle the Z axis. I 
wrote a utility that would search for non-zero Z values and offset the 
coordinates by a few feet so they wouldn't appear to intersect with the 
street below. 

A lot of geodata needs a little groom and clean so it will route cleanly.
