I have some questions about Alabama State Route 20's path. I've always been curious about this route, as traces of it seem to be all over town.
From squinting at some old maps, I'm trying to figure out AL 20's path from Huntsville towards Decatur. What I can piece together is that it was a circuitous bit of stair-stepping:
- West on Old Madison Pike
- South on Hughes Road
- West on Mill Road
- South on Church Street
- Right (west) on Main Street for a little stretch...
But did it go north or south on Sullivan Street (?)
I can't tell if it was then routed on Mill Road (closest to Main Street), Palmer Road, or Madison Boulevard.
What I do know is that it must have been routed for a bit onto County Line Road, so it could "get" to Old Highway 20, went left onto Mooresville Road, south towards Belle Mina, swung down through Mooresville, and onto Decatur using the old alignment left by the 65/565 complex (rejoining present-day AL 20).
For that matter, where did AL 20 join up though downtown Huntsville? I'm a bit confused, but I'm guessing it probably joined Whitesburg Drive at some point.
Thanks for any help on this.
