What are the three types of work zone configurations?

The correct answer outlines three distinct approaches to manage traffic flow while maintaining safe work zones. Each configuration is vital for ensuring that roadwork can proceed while minimizing disruptions to vehicular movement and maintaining safety for both workers and drivers.

Lane closure refers to the restriction of one or more lanes due to work being performed, which may allow traffic to continue flowing, albeit in a reduced capacity. It's often used for tasks that can be completed with minimal impact on overall roadway usage.

Detour involves redirecting traffic away from the work zone entirely, typically onto a parallel route, which is necessary when the work being performed necessitates a full blocking of the road or when safety cannot be ensured with traffic passing through the area.

Partial closure implies that, while some lanes remains available, a portion of the roadway is restricted, which can be managed more flexibly than a complete closure.

Each of these configurations serves a purpose in traffic management and impacts how construction and maintenance activities can proceed safely. The identification of these configurations helps ensure that traffic is managed effectively around work zones, maintaining safety and efficiency.
