Temporary Traffic Control/Work Zone

Purpose

Work zones directly impact the safety and mobility of road users and highway workers. Addressing safety and mobility issues requires considerations that start early in project development and continue through project completion.

When to use this subject

You must consider temporary traffic control on all projects, including non-MnDOT-initiated projects on the trunk highway system (e.g., city- and county-initiated projects). This is for all modes of travel, including Active transportation.

For specific process information, see the other guidance, Work Zones-Temporary Traffic Control website, and/or contact the individuals on the contacts page.

How this subject fits into the overall project development process

You should consider temporary traffic control (TTC) during all phases of the project, from scoping through construction. TTC concepts should be developed during the scoping/preliminary design phase. Project managers, along with traffic, construction, design and maintenance personnel should work together to determine the impacts of the project, which are then detailed in the Transportation Management Plan (TMP). The TTC plan is developed during the design phase. Regular reviews of TTC operations should be conducted throughout construction of the project.
