A KMZU listener reported around 5:20 p..m. of an incident on southbound MO 13 in Warrensburg, just south of US 50 Highway.  A truck carrying an oversized load could not get through the round-a-bout and has caused the closure of that area, including the on and off ramps to the highway.  The listener reported that the truck has been there a while.  Troopers and emergency crews are in the area.  Use caution while driving on Mo 13 and US 50 junction as they work to clear the scene.
