Attention to the safety of travelers is especially important in work zones.

The workspace is the area closed to traffic and set aside for workers, equipment and material. Work zone signing items such as regulatory signs and Type III Movable Barricades and other work zone items such as Changeable Message Signs, flashing arrow panels, channelizing devices, lighting devices and signals are specially designed to minimize risk to workers and travelers. Pavement edge treatment is frequently included in work zones as are practices such as crossovers, temporary connections and detours.

The work zone duration and location of work are discussed in this article. There are many aspects to be considered when inspecting construction quality and this article provides construction inspection guidelines.

Temporary traffic control devices warn motorists of hazards, advise the proper path through the work area, delineate areas where travelers may not operate and separate them from workers and opposing traffic. Whenever worn or damaged devices appear in a work zone, the general quality of the work zone deteriorates. To avoid this, MoDOT has provided quality standards for temporary traffic control devices.

To provide uniform flagging and to train employees how to protect themselves, co-workers and travelers, MoDOT requires flagger training.

Every day MoDOT has many work zones on Missouri's highways. MoDOT is committed to providing safe and efficient movement of both motorized and non-motorized traffic through or around temporary traffic control work zones and providing protection for workers and equipment located within these work zones. To better educate technicians and those designing and managing temporary traffic control work zones, Work Zone Technician Training, Advanced Work Zone Training, MoDOT Work Zone Guidelines and Work Zone User Training is available.
