Mini Interchange

In 2011, this mini interchange was first designed by Xu Li, a Chinese college student majored in transportation, to solve the traffic problem of Shuangjing Bridge, Chaoyang District, Beijing.

Expert Lin Ma said this interchange has many problems:

First, it's hard to build such an interchange. If this interchange is actually built, considering slopes and corners, it could not be "mini" any more. I agree with this after constructing it in assets creator.

Second, it has so many corners. Vehicles get slow when they are turning. So these corners would cause new traffic jam.

Third, those slopes could make vehicles skid in bad weather.

Fourth, so many blind spots there could cause accidents.

However, it's okay to use this in game. I made this interchange just for fun. If you guys have any good ideas, feel free to tell me in comments.
