When California State Route 180 was commissioned in August 1934 the alignment in took in Sierra Nevada range was very different than from today. The original highway alignment from Squaw Valley (now Yokuts Valley) to east Grant Grove (then part of General Grant National Park) originally followed what is now Ruth Hill Road, Dunlap Road, Pinehurst Road (modern California State Route 245), Dark Canyon Road (partially now Forest Road 14S45). After funding fell through for the planned Kings Canyon Road the was corridor eventually picked up as a 30-mile-long cooperative project between the Division of Highways and Federal Government. Much of current alignment of California State Route 180 bypassing Squaw Valley (now Yokuts Valley) and Dunlap was complete by 1941. The post-1941 alignment of California State Route 180 in Squaw Valley was shifted onto what was once Dunlap Road in Squaw Valley. This alignment itself was later bypassed by modern California State Route...
Because every road has a story.
