I'd say that definition is unusual, even in
the US. In common usage, a
limited-access highway is a divided highway, with no cross roads--instead
using on & off ramps.
The USGS offers this common-sense definition:
Limited Access Highway: A route that is part of the United States Interstate
Highway System or other similar expressway.

In fact, "expressway" seems like a good synonym (to my very US-centric
ears).
