Unsupported Advanced Island Redux 2.3

It's been a long time coming, but finally I've gotten the map to a point where I can release a new update. At first, the changes might not seem major, but I've redone almost all highway to add smoother banking. A few spots of bumpiness may remain: I'm only one person and I probably didn't find every mess-up or bug.The decal roads' break angles have been increased to make those roads appear smoother, along with the AI mapping. I've added some trails, a jump, and two new roads.

I've also made the decision to cut down the amount of sidewalk in the "city" area. I did this because I found the sidewalk to be irritating when driving through as it would grab my tires. I removed it to allow you to drive smoothly throughout most of the city. Sidewalks remain in the housing development area.

As always, I hope you guys enjoy this update. If you spot any bugs, un-smooth surfaces, floating tress or lampposts (I hopefully got them all), please let me know.
