New Jersey is known for a lot of things: beautiful shorelines, strong accents, and — whether you like it or not — not being able to pump your own gas. It is also where Jersey Barriers come from. You may not realize it, but you see them all the time.
The Jersey Barrier — also known as a Jersey Curb, K-rail, or Jersey Wall — refers to the barricades you see along the center and sides of highways, at construction sites, in parking lots, and pretty much anywhere traffic is being directed. They are often made of concrete, especially for permanent installations, but are also seen as the more portable bright orange and white plastic versions that are filled with sand or water.
