There's a local racetrack here in Waterford, Michigan, US (north of Detroit) which hosts road bike races. It really is a great use, because it's a closed/non-open-to-public route which is generally well paved and free of the usual road debris (gravel, grass, car parts, glass).

Bicycle road races are otherwise pretty complicated to put on, because they require a section of road that can be closed (eg: private industrial park / campus), sometimes work done to the road to clean it beforehand, etc. Using a race track has a lot of this done for you.
