Avenue over sunken avenue.

[ShadeSlayer]

Right now, I am trying to accomplish a Diagonal Avenue over a diagonal sunken avenue (or basically a diagonal bridge). Am I looking in the wrong place, or has this not yet been implemented in NAM?

To my knowledge, diagonal on-slope puzzle pieces for avenues haven't been created yet. You could convert the crossing avenue into a Maxis highway and use the diagonal highway puzzle pieces as a workaround, though.
