Recommendation on route from New Orleans to Memphis via Highway 61

[Zoomidee]

I'm planning a bikepacking trip in October starting in New Orleans and heading to Memphis. The plan is to stay as close to Highway 61 so as to take in the Delta blues along the highway. I know it's not the most picturesque, but it's not all just for the biking.

The Natchez Trace has some coverage but then heads out NE away from Highway 61 to Tupelo. I have some info from the Great Rivers South map.

Hoping to connect with some locals who could guide me to crafting a way. It's about 500 miles and we're taking 5 days so it's not too strenuous a trip.

This is the best resource i've found so far... http://www.crazyguyonabike.com/doc/Highway61Revisited

Thanks!
