Jersey barriers, also known as jersey walls, are a type of modular concrete barrier commonly used in transportation infrastructure and construction projects. They are vertical or slightly inclined structures made of reinforced concrete, typically measuring around 3 to 4 feet (0.9 to 1.2 meters) in height, and are designed to redirect or separate traffic, enhance safety, and provide physical barriers.
These barriers are named after the state of New Jersey in the United States where they were first implemented. They consist of precast concrete units that interlock with each other to form a continuous barrier. Jersey barriers usually have a distinctive shape, resembling an inverted "T" or a trapezoidal prism, with a wider base and a narrower top. This shape makes them stable and resistant to being easily toppled by impact or wind forces.
Jersey barriers are widely used in various transportation applications, including highways, roadways, bridges, parking lots, construction zones, and other areas where traffic needs to be regulated or divided. They help prevent vehicles from crossing into opposing lanes, provide protection for workers, and reduce the likelihood of accidents, especially head-on collisions. They are effective at minimizing damage caused by errant vehicles and can withstand high impact forces.
In addition to their use in traffic management, jersey barriers are also utilized as protective barriers against natural disasters such as floods, hurricanes, and landslides. They can be filled with water for added weight and stability, creating water-filled barriers or portable flood barriers.
Overall, jersey barriers play a crucial role in ensuring public safety, acting as versatile and reliable barriers in various settings to guide, control, and safeguard traffic flow.
