Back in 2016 after returning from Phoenix I made a couple stops on old alignments of US 60/70 in the Sonoran Desert; Chuckwalla Valley Road and Ragsdale Road. Chuckwalla Valley Road was bypassed by I-10 in the late 1960s and is mostly known for being the road that went to "Hell." Hell was a small road side community which was demolished during the construction of I-10. Former US 60/70 in Desert Center was on Ragsdale Road which extends a couple miles west of the community acting as a north frontage road of I-10. Interestingly the Ragsdale Road Tex Wash Bridge withstood floods better in 2015 than I-10 did as the eastbound lanes washed out.

Chuckwalla has been closed off for a few years now. GE imagery shows several places where sand has washed over the road, and two bridges that have cones on them, although they otherwise look intact. But given that it doesn't even go to Hell any more, I can't imagine them fixing that piece of road, ever.
