Jersey Barrier, K-Rail

Jersey Barrier, K-Rail: These are various names for different types of those temporary concrete highway barriers. Tommy Lee Jones called them K-rails in the scientifically-silly disaster movie Volanco. The Jersey barrier was invented by the New Jersey highway department, and some engineer might imagine that the cross-section of a k-rail resembles a k. The different names for long, portable concrete barriers are only interesting to highway engineers, and I doubt many of them even care to differentiate a k-rail from a Jersey barrier.

Sacki jumped from his perch on a jersey barrier and ran to a Mitsubishi Pajero, gunning the engine.
