The highway/freeway, is a medium sized road with multiple entrances and exits, that serve no purpose currently. They have four lanes like real highways. They don't have any turns/curves in the road, neither does it have any traffic lights.
The highway/freeway is mostly gray, (except for the road on it) has a barrier to keep cars from falling off, there are a few entrances and exits placed randomly on one side of the place. There are multiple support beams under it. The road itself is mainly gray with some white paint for outlines, and lanes. The gray area starts right after the ramps end.
