Drove the entirety of CA 174 this morning between CA 20/49 and I-80. There wasn't too much special about the highway but the Empire Mine on the outskirts of Grass Valley was worth a stop. My photos are below, I'll probably have a blog post ready this weekend on the history of CA 174:

Finished up my blog write up on CA 174. Nothing too exciting with the route here but the Empire Mine was a pretty cool side trip:
