The first concrete median barriers were predated today’s more manageable Jersey Barriers and were used in the mid-1940s on US-99 on the descent from the Tehachapi Mountains in the central valley south of Bakersfield, California. That first generation of concrete barriers was developed to:
(a) minimize the number of out-of-control trucks penetrating the barrier, and
(b) eliminate the need for costly and dangerous median barrier maintenance in high-accident locations with narrow medians – concerns that are as valid today as they were 80 years ago.
The Plastic Jersey barrier, also called the New Jersey wall, was developed in the 1950s (introduced in its current form in 1959)
According to Wikipedia A Jersey barrier, Jersey wall, or Jersey bump is a modular concrete or plastic barrier used to separate lanes of traffic. They were designed to minimize vehicle damage if bumped into and preventing vehicle crossovers that could result in head-on collisions.
Head-on vehicle collisions are minimized by gradually lifting the vehicle and pivoting it away from oncoming vehicles and back into traffic heading in its original direction.
Plastic Jersey barriers are also used to reroute traffic and protect pedestrians. They are often seen being used to protect drivers and workers during highway construction as well. A fun fact is that they are named after the U.S. state of New Jersey which first started using the barriers as separators between lanes of a highway in the 1950s.
Over time, different variants of the jersey barrier have been created but these more modular variants, including plastic water-filled barriers, were created and stand out for their usefulness as temporary barriers.
Jersey Barrier Designs include two rectangular notches at the bottom (through the short axis) to allow for forklift-style lifting by front-end loaders. Barriers meant for short-term placement, especially in military and security barrier uses, might include steel rebar loops embedded in the top surface for rapid hook-and-cable system lifting.
