Temporary Traffic Control Operation
The maintenance work directs traffic through a short term lane closure. According to Minnesota Statute 169.06, Subd. 4(e), a flagger is permitted to stop and hold traffic as necessary to ensure the safety of highway workers and the motoring public.

Work Zone Safety Resources
A work zone (also known as a Temporary Traffic Control (TTC) Zone) is an area of a roadway where road user conditions are changed because of a work space or incident by the use of TTC devices, flaggers, uniformed law enforcement officers or other authorized personnel.
The type of operation planned, space requirements, time duration, and roadway characteristics for a specific TTC Zone will determine the appropriate procedures and preparation needed for the work zone.
Safety in the work zone is the primary consideration to be addressed in a TTC plan. A work zone may be as small as a single worker stopping along side the roadway, to a mobile maintenance operation, to a flagger controlled lane closure, to a reduction of lanes on a multi-lane roadway and up to detoured traffic for a full roadway closure. The TTC plan must provide a safe work place, and a safe route for the pedestrian and the motorists.
Various laws, policies, standards, guidelines, and information are required to provide for this safety. The documents found through this page are a collection of Work Zone Design Tools which provide guidance to the project planner, temporary traffic control designer, contractors and field personnel. These tools are found in the Quick Links on the right-side menu of this web page. The tools include manuals, guidelines on current practices, reports on past studies, the latest technical memorandum related to Traffic Engineering topics, standards for various TTC devices, and the collection of special provisions boilerplate. The Template Sheets include typical plan sheets for various traffic configurations. The sheets help provide uniform statewide TTC designs.
