Work zone speed limit

In Minnesota, design speeds used for designing work zone geometrics depend on design speeds of approaching and departing roadways.
Methods found to be effective for motorist compliance include: Trooper on site with flashing lights, PCMS with messages: “Trooper on Site” and “Speed Limits Enforced.”
Also see Mn/DOT’s Work Zone Speed Limit Guide on the web site below.
