Just drove the section between Apache Junct. and the summit of 60 to the east. That's some nasty riding in there. It wouldn't be so bad going east-west because you'd be headed downhill and get through it quickly. I saw one guy pushing his loaded bike uphill headed east. Did not envy him. Watch out for that bit for sure--high traffic, trucks, many places with no shoulder. Ugh. Might want to check into riding around the north side of the Superstitions, but that will have it's own challenges for sure.
Best of luck! I'm feeling the need for another long tour. Haven't been on one since 2012.
This section of US 60 is part of why we did a major reroute on the Southern Tier in late 2015: Major Route Change: Southern Tier in AZ and NM.
