Outdoor writer Tom Stienstra wrote "Of all the paved roads in California, a 5-mile section of Iowa Hill Road in the Sierra foothills is among the narrowest, curviest and steepest. In one stretch, the road is carved into a canyon wall that towers over the North Fork American River, with a precipitous drop below to your right.[2] Sierra Nevada Geotourism says "the winding and very narrow road is dangerous with steep cliffs and not recommended for trailers."[3] Roseville, California journalist Todd Schofield calls a trip on the road an "adrenaline-rush, white knuckle journey".[4]
The road formerly crossed the Iowa Hill Bridge, a wire suspension bridge that was built in 1928.[5] A more modern bridge was built in 1985, and the old bridge is now a pedestrian bridge.[6]
