The center part for an A-type barrier typically refers to the main horizontal component that runs along the top of the barrier. The A-type barrier, also known as a New Jersey barrier or concrete barrier, is a common type of traffic barrier used to separate opposing lanes of traffic on highways and roads.

The center part of the A-type barrier is the critical section that provides the primary separation and containment for vehicles. It is made of reinforced concrete, designed to withstand the impact of vehicles and prevent them from crossing into oncoming traffic or leaving the road.

The A-type barrier's design, shaped like an inverted "A" or "V," allows for gradual deflection of vehicles that collide with it, reducing the severity of impacts and redirecting the vehicles away from traffic flow. The center part of the barrier plays a significant role in this redirection and containment process.

These barriers are an essential safety feature on highways and roads, helping to reduce the risk of head-on collisions and providing a protective barrier between opposing lanes of traffic. Their use is widespread in various transportation infrastructures globally.

Used during road works and similar activities to cordon off areas, close roads or direct traffic. Ideal for parades, public events, parking lots and other closures
