I love it. But highways aren't 2-lanes on both sides, thats a Avenue. :|
You did a great job. :) Cookiez for u 9/10
EDIT: Well, Highways can turn into 2 lanes for both sides, when they pass exits. But avenues are typically 2 lanes on both sides INLESS they are NOT High density.
High Density are 3 lanes; Kind of like a highway, but not. You see them in areas like, Chicago, SanFransisco. Some areas have streetcarts in the center; For instance, SanFransisco.
