The Highway is a road system which loops around the city. Most of it is elevated, and the entrance of this road system is in the north part of the city (unelevated). The Highway is also the current homeowner of the Highway Race.
It is not useful for getting around town, as there are no exit ramps, and the only way to get off is by flipping your car over the embankment. It does, however, provide an excellent place to watch the Airport Quarter Mile Race.
The Highway is also useful for grinding by driving around it for long periods of time.
The outer ring is around 2.81 km (1.75 miles), and the inner ring is around 2.67 km (1.66 miles).
