Lafarge Precast Edmonton Concrete New Jersey Barrier Transitions are used in conjunction with our standard 4030 barriers across Edmonton and Alberta. Jersey barriers are also used to reroute traffic and protect pedestrians and workers during highway construction. Federal Highway Administration (FHWA). The Ohio Department of Transportation (ODOT) mandates specific design requirements for their precast concrete barrier walls. , The Jersey barrier, also called New Jersey wall, was developed in the 1950s (introduced in current form in 1959), at the Stevens Institute of Technology, New Jersey, United States, under the direction of the New Jersey State Highway Department to divide multiple lanes on a highway.

He orders Jersey barriers, referring to them by the California name, K-rails, to be set up double-stacked in a horseshoe shape, which, combined with flooding the dammed-up lava with water, halts the lava flow. A Jersey barrier, Jersey wall, or Jersey bump is a modular concrete or plastic barrier employed to separate lanes of traffic. .

Concrete, Jersey Barriers, New Barriers, Utility & Non-DOT; 10′ Jersey Barrier; Also referred to as “K-Rail” or “Concrete Traffic Barrier,” a precast jersey utility barrier is a standard in perimeter security. Concrete. Cross-sectional dimensions shall not vary from design by more than ¼ inch. The F-Shape has been found to be more effective overall than the Jersey Shape barrier in some instances. This is particularly advantageous when constructing barriers on curved ramps.  The states of New York, Massachusetts and New Jersey have adopted the taller barrier for their roads, as compared to the standard 32 inches (81 cm) suggested by the Federal Highway Administration. The F-Shape is more commonly used for permanent concrete barriers.  A typical Jersey barrier stands 32 inches (81 cm) tall and is made of steel-reinforced poured concrete or plastic. , The UK equivalent is the concrete step barrier. "K-rails" redirects here.

These lower dividers are visible in old photographs. Security Bollards. , Modern variations include the constant-slope barrier and the F-shape barrier. A large mass of reinforced concrete that absorbs impact and resists penetration through a controlled deflection of the barrier.  Standing at 42 inches (107 cm), it is 10 inches (25 cm) taller than the standard Jersey barrier. Even Route 46 had the rumble strip in many places before gradually, the higher barrier was installed. This barrier design has been credited with effectively containing and redirecting larger vehicles, including semi-trailer (tractor-trailer) trucks.
