Design and oversight of work zone operations

In West Virginia, work zones are addressed in different ways, depending upon the scope of work.
For small projects or routine maintenance work, work zones may be established in accordance with an appropriate standard traffic control case. On construction projects, the project designer will select a standard case from the traffic control manual with the necessary pay items and quantities included in the contract plans. The contractor (or a traffic control subcontractor) is responsible for installing, maintaining, and removing temporary traffic control devices.
On larger projects, the roadway designer is responsible for setting up a sequence of operations and preparing a temporary traffic control plan for each construction phase. The contractor (or a traffic control subcontractor) is responsible for installing, maintaining, and removing temporary traffic control devices. Most temporary traffic control on larger projects is subcontracted to specialized firms.
Where a railroad or utility is involved, that entity is normally responsible for all traffic control unless the location, duration, or complexity of the work dictates that it would be in the interest of the motoring public that others perform or assist with the traffic control.
Oversight is normally carried out by the project supervisor and the Assistant District Engineer – Construction on construction projects; by the District Utilities Supervisor for railroad or utility activities; and by the Assistant District Engineer – Maintenance for work by State forces. District or Headquarters Office Traffic Engineering staff may be consulted as circumstances warrant.
Policy is set by the Traffic Engineering Division, with the approval of the Commissioner of Highways.
All traffic control must first and foremost be in conformity with the Manual on Uniform Traffic Control Devices.
