This is a El Norte clon so you can find all those things as during a mission.
In additional work I created a long and rumbling racetrack including AI cars,
so you can see how bad I'm driving.

This Track is even made for smooth riding but missused for racetrack.

I also added two elevated Roads, for you can find the entrance on to.
They later have been connected, so some parts look messed with. 

What can I do if I can't modle new bridges or roadblocks.

Nevertheless it was very difficult to inbed those elevated road in this map.

But it looks great now. This elevated Roadblocks have been used in "Ante the duell" before.

Have fun, and it would be easy for you to win against my AI.
