A Jersey barrier , Jersey wall , or Jersey bump is a modular concrete or plastic barrier employed to separate lanes of traffic. It is designed to minimize vehicle damage in cases of incidental contact while still preventing vehicle crossovers resulting in a likely head-on collision. Jersey barriers are also used to reroute traffic and protect pedestrians and workers during highway construction.

They are named after the U. The barriers are also known as a K-rail , a term stipulated in the California Department of Transportation specification for temporary concrete traffic barriers which first started using concrete median barriers in the mids. Over time, different variants were created. Taller variants, such as the Ontario Tall Wall , proved more effective at stopping vehicles and had the added advantage of blocking most oncoming headlights.

More modular variants, including plastic water-filled barriers, have been created. Although it is not clear exactly when or where the first concrete median barriers were used, concrete median barriers were used in the mids on U. This 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 Jersey barrier, also called New Jersey wall, was developed in the s introduced in current form in , at Stevens Institute of Technology , [4] New Jersey , United States, under the direction of the New Jersey State Highway Department to divide multiple lanes on a highway. Their widespread use in road construction has led to wide application as a generic, portable barrier during construction projects and temporary rerouting of traffic into stopgap carpool and rush-hour reversing highway lanes.

Most of the original barriers constructed in New Jersey in the s and early s were not «modular»; they were poured in place the way curbs are. Many of the first installations Route 46 in Bergen County and Passaic County, for instance were much shorter than the heights discussed here, typically about two feet 61 cm tall. Some dividers on county or local roads may have been lower than that since they replaced a raised concrete rumble strip that would dissuade, but not prevent, traffic crossing from one lane to another.

Even Route 46 had the rumble strip in many places before gradually, the higher barrier was installed. These lower dividers are visible in old photographs. When the Bergen Mall was first opened in Paramus, these rumble strip dividers were extensively used on the roadway Forest Avenue that separated the grocery stores from the mall proper.

The design of the Jersey barrier was specifically intended to minimize damage in incidental accidents and reduce the likelihood of a car crossing into oncoming lanes in the event of a collision.

In common shallow-angle hits, sheet-metal damage is minimized by allowing the vehicle tires to ride up on the lower sloped face. 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.

Modern variations include the constant-slope barrier and the F-shape barrier. The F-shape is generally similar to the Jersey barrier in appearance, but is taller, with somewhat different angles. The UK equivalent is the concrete step barrier. Ontario’s Ministry of Transportation is replacing guiderails steel guardrail and steel box-beam with these tall wall barriers on series highways since the early s, while the City of Toronto is doing likewise on portions of the Gardiner Expressway and Don Valley Parkway.

The New Jersey Turnpike Authority developed and tested a similar, but heavily reinforced, design. This barrier design has been credited with effectively containing and redirecting larger vehicles, including semi-trailer tractor-trailer trucks. Designs with two rectangular notches at the bottom through the short axis 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.

The G Toronto summit used modified modular Jersey barriers with wired fencing bolted onto the concrete. The fence used the barrier as sturdy base to prevent protesters from toppling the fence around the security zone at the Metro Toronto Convention Centre. The U. Sometimes they are deployed to form a chicane to slow vehicular traffic arriving at military installations or other secure areas.

The Ohio Department of Transportation mandates specific design requirements for their precast concrete barrier walls. Without this marking, a barrier wall is not approved for use in Ohio. Hollow polyethylene barriers have been developed for short-term applications where portability is important.

These plastic barriers are normally filled with water after placement on-site to provide a moderate level of crash protection, then emptied prior to removal. Jersey barrier. Article Talk.

– Jersey Barriers: Names and Variations | Plastic Jersey Barrier

 

There are different varieties that you must have seen in your daily life. Have you ever seen those large, boxy blocks scattered around construction zones and wondered what they were called? Where did the name jersey barrier come from are jersey barriers, where did the name jersey barrier come from in this blog post, you will get a better picture of why they’re called that, the different where did the name jersey barrier come from of jersey barriers for saleand the benefits of using them.

Often seen on highways and other busy roads, Jersey barriers are traffic barriers designed to protect drivers and pedestrians from errant vehicles. Also known as K-rail barriers, they are made of concrete and typically have a length of 3. These barriers are one of the most common traffic barriers in use today.

While They are often used to separate opposing lanes of traffic, they can also protect pedestrians from oncoming traffic. In addition, these can be used to shield vulnerable areas from vehicular damage, such as utility meters or building foundations. These barriers, also known as K-rails, have become a common sight on roads and highways across the country.

But why are they перейти на страницу Jersey barriers? The answer lies in their history. Initially developed in the s by the New Jersey Turnpike Authority, these barriers were designed to reduce the severity of vehicle accidents.

The barriers get their name because they were first used on the New Jersey Turnpike. Since then, these barriers have been adapted for use in various settings, from construction sites to parking lots. Thanks to their durability and flexibility, these barriers have become an essential part of road safety перейти на страницу. There are three main barriers based where did the name jersey barrier come from the material made from concrete, plastic, and steel.

Concrete barriers are the most common type of barrier. They are made from cement, water, and aggregates such as sand or gravel. Concrete barriers are solid and durable, making them ideal for high-traffic areas. However, they are also cumbersome, making them difficult to move and install. Plastic barriers are made from materials, including high-density polyethylene HDPE and recycled plastic. Plastic barriers are lightweight and easy to transport and install.

However, they are not as durable as concrete barriers and where did the name jersey barrier come from be damaged by UV rays or extreme temperatures. Steel barriers are made from sheets of steel that are welded or bolted together. Steel barriers are robust and durable, making them ideal for high-traffic areas. The most common type is the W-beam, which separates traffic where did the name jersey barrier come from highways and other high-speed roads. These barriers are usually made from steel or concrete and can be up to 12 feet long.

Another common type of jersey barrier is the C-channel, which protects against vehicle collisions in lower-speed areas such as parking lots and school zones. These barriers are shorter than W-beams and are often made from recycled plastic. M, U, and J-shaped barriers are typically used in construction zones to protect workers and equipment from oncoming traffic. Whatever the shape or design, jersey barriers play an essential role in keeping drivers and pedestrians safe.

These barriers are an essential part of road safety infrastructure. Here are some of the benefits of using them:. While these barriers are an essential tool for road safety, there are a few things to keep in mind while setting them up:.
