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. (http://www-atlas.usgs.gov/metadata/roadtrl020.faq.html)
In fact, "expressway" seems like a good synonym (to my very US-centric ears).
Would you call this an expressway? http://en.wikipedia.org/wiki/Image:San_Tomas_Expressway.jpg A number of states do, both in official and common usage.
