What equipment is often used for lane closures in work zones?

The use of temporary barriers or concrete jersey barriers for lane closures in work zones is essential for several reasons. These barriers provide a solid physical separation between moving traffic and the work area, significantly enhancing safety for both road workers and drivers. They are designed to minimize the risk of vehicles crossing into the work zone, thereby reducing the likelihood of accidents.

Temporary barriers are effective in redirecting traffic and maintaining traffic flow while also protecting the workers who are on the job. Their stable structure makes them suitable for various conditions, including high-speed roadways, where other forms of traffic control might be less effective.

While traffic cones and portable signage can help in guiding traffic, they do not offer the same level of protection as concrete barriers. Cones can easily be displaced by wind or vehicles, and portable signage may not convey sufficient warning of hazards. Wire fences are typically used for different purposes, like securing an area, and are not effective for controlling traffic lanes in a work zone. This makes the use of temporary barriers or concrete jersey barriers the most appropriate and safe choice for lane closures in such situations.
