What Does K-Rail Mean?

A K-rail is a modular concrete or plastic traffic barrier used to separate lanes of traffic. They are commonly used to reroute vehicular traffic during roadworks and delineate the construction zone. Other uses for k-rails include site security, flood defense, edge protection and temporary military barriers.

K-rails are also known as Jersey barriers or Jersey walls.

Trenchlesspedia Explains K-Rail

Although trenchless construction can be carried out with minimum impact to roadways, many times, vehicular and pedestrian traffic need to be rerouted to ensure the safety of construction workers and the general public. K-rails, which serve as barriers to restrict access to the construction area, are a key element in the process known as work zone traffic control.

K-rails are also designed to dissipate energy from vehicular impact by deflecting the vehicle rather than absorbing the entire impact force.
