Orange and white Plastic Jersey barriers have been seen on highways and roads throughout North America for over 50 years. They are often used as medians to separate lanes of traffic. They are also used to block off restricted or dangerous areas during highway construction or repair projects, and to channel vehicles through a construction area.
Due to their bright color, Plastic Jersey barriers provide higher visibility to motorists than concrete highway barriers, reducing the potential for collisions. Even when they are struck, they minimize damage to vehicles. Their polyethylene material requires less maintenance than concrete and results in a longer life span.
