Our RVing adventures have taken my wife and I to the most westerly place you can drive in the United States along with the most southerly. We have seen the northern most of this and that including the most northern Denny’s restaurant in the world. We have also traveled to the shortest river. Now we can add RVing the shortest highway in California to the list. In the small town of Coloma near historic Sutter’s Mill just off Highway 49, you will find State highway 153, California’s shortest route, measuring a scant 0.55 miles long. The route takes you to Marshall’s Gold Discovery Monument. Given the fact that the road is also narrow (16’) it also qualifies as an adventure in RVing. Enjoy!
