What type of barricade is typically used for horizontal lane closures?

Type I and Type II barricades are specifically designed for traffic control in various applications, including horizontal lane closures. These barricades are portable and provide a clear visual indicator to drivers of lane adjustments or closures. Their design helps direct traffic safely and effectively around an obstruction while maintaining visibility for both the drivers and the traffic control personnel.

Type I barricades are generally used for situations where limited visibility is required, and Type II barricades provide more visibility and are often utilized in areas needing additional attention due to higher traffic volumes. Because of their sturdy construction and the ability to display warning signs or messages, Type I and II barricades are the preferred choices for managing traffic flow during lane closures in a safe manner.

Plastic cones and signal lights also serve important roles in traffic management, but they do not provide the same level of barricade-like effectiveness as Type I and II barricades for horizontal lane closures. Plastic cones are often used for temporary or minor deviations in traffic, while signal lights are typically used to control traffic flow rather than provide physical barriers. Type III barricades are larger and more suited for road closures or major blockades rather than horizontal lane adjustments.
