The Missouri Department of Transportation (MoDOT — pronounced "MO-dot") is a state government organization in charge of maintaining public roadways of the U.S. state of Missouri.
MoDOT has been one of the leaders in the construction of the diverging diamond interchange, having built the first such interchange in the United States (June 2009 in Springfield) and the most of any state (six as of September 2012).
