What is the minimum required length of portable concrete barrier sections?

The minimum required length of portable concrete barrier sections is 10 feet. This standard length is established to provide sufficient barrier effectiveness while also ensuring ease of movement and placement on work sites. A barrier that is 10 feet long offers adequate protection and helps to properly redirect vehicles that may accidentally enter a work zone, reducing the risk of serious accidents.

Shorter sections may not provide the same level of safety or impact resistance, which could lead to gaps that reduce the overall effectiveness of the barrier in protecting workers and drivers. Longer sections, while potentially providing more robust protection, may be impractical for transport and installation purposes, complicating the logistics of setting up and removing barriers as needed. Therefore, 10 feet is a balance, making it the optimal choice based on safety and operational efficiency.
