I guess it depends on exactly how you define a roadway, specifically how it differs from a scenic track.

If the difference is simply that a roadway models an every day road, whereas most tracks model race tracks, then yes, people have done it.

Rallyhub's Flat Over Crest brilliantly models a typical British village, which is being used as a rally stage. In a similar vein, though in very different places, Hub's Swedish Rally Track and Dakar Track are also presumably based on ordinary, every day roads rather than custom built racing circuits.

As I said though, it depends on your definition of a roadway.
