K-rail barriers are an excellent solution for keeping work crews, motorists, and construction sites safe while maintaining traffic efficiency and maximizing your work area. Our K-rail barriers can be utilized for permanent or temporary applications depending on project specifications. Carolina Traffic Devices offers a wide variety of concrete barriers engineered to meet DOT standards, plus more affordable, non-DOT approved options. K-rail barriers are a sturdy, low-maintenance choice for construction zones, roads, and anywhere else where pedestrians and vehicles must be kept apart.


Carolina Traffic Devices offers road and traffic barrier solutions from Virginia to southern Georgia. In addition to offering loading and transportation, we carry barrier accessories, such as painted barriers and glare screen. We also supply high-quality delineators (reflectors) and sturdy impact attenuators (crash cushions) to attach to your concrete barrier.

A Range of Options to Fit Your Project Specifications

Explore our range of K-rail barrier options to find the right one for your next project.


New or Used: Whether you’re looking for brand new K-rail barrier or a more affordable used option, we’ve got you covered.

Non-DOT Approved K-Rail Barrier Wall: These barriers no longer meet current DOT standards, but are suitable for use on many non-DOT projects. They may have been damaged or were simply poured using an old specification.

Used, Non-DOT Approved K-Rail Barrier Wall: We offer two options for used, non-DOT approved K-rail barriers. “Decent” means minor damage; the barrier may have small cracks or pieces missing, but its connections are intact. These barriers would meet quality standards on a DOT project. “Damaged” indicates significant wear and tear, including larger cracks or pieces of concrete missing. Connections may not be intact, and this barrier would not meet quality standards for use on a DOT project.
