A US highway is an all access highway, like a main road; it includes businesses, houses, and direct intersections. Top speeds on the average US highway are 55 mph. An interstate highway is a limited access highway that is meant for commute. It includes no property entrances, and interchanges at high speed. Speeds range from 65 to 75 mph (about 90 to 105 km/h).
Warrego Highway is open as of 14/1/11 from Toowoomba to Dinmore with reduced speeds on many sections.
I don't use mine until I reach highway speeds.
