I think my favorite bit though is where they talk about essentially enclosing the stretch of Main St within the loop in a fully covered, air-conditioned mall - complete with moving walkways and/or shuttle cars to facilitate traversing the length of the strip. What a wild image!

Anyway, I'll probably read more in the near future. They're an interesting bit of planning history. I'm disappointed that we've failed to pedestrianize these spaces despite recommendations for over half a century.
