I saw where a few asymmetrical roads were in the works. Awesome! I wanted to make a suggestion to add a some other types of asymmetrical roads. I'd like others to weigh in too.

• 7-lane (2 incoming and 5 outgoing: 2 left turn dedicated, 2 through dedicated, 1 right turn dedicated)
  
• 6-lane (2 incoming and 4 outgoing)

These would typically be used at intersections to move more traffic at each signal phase. Mayors would be able to specify the configuration of the outgoing lanes using Traffic Manager: President Edition.
