Yes, the overview plans show a dotted path that the Midtown Corridor would take, but the more detailed view does not show it. The bike path seems to be in the way of where the tracks for the Midtown Corridor would be.Isn't slide 11 what you're looking for?The detailed diagram also does not show how the connection with the Midtown Corridor would fit, only the more generalized diagrams at the beginning show it.
Franklin has an accessible ramp on the north side, but not on the south side. It really does need those circulation towers at both ends. I doubt people would go up the wrong side of the Street at West Lake, and then dash across the street, but forcing people to wind up or down the ramps is less than ideal.
