Wikipedia: http://en.wikipedia.org/wiki/Jersey_barrier

A Jersey barrier or Jersey wall is a modular concrete barrier employed to separate lanes of traffic. It is designed to both minimize vehicle damage in cases of incidental contact while still preventing crossover in the case of head-on accidents.

Also utilized extensively to re-route traffic and protect pedestrians during highway construction, such barriers are increasingly deployed in anti-terrorism roles as both quick fixes and semi-permanent protections against perceived landborne threats.

Jersey barriers are known colloquially by a variety of names in the U.S., including K-rail in the western states, a term borrowed from the California Transport department specification for temporary concrete traffic barriers.
