Many of you still appear to be confused by one section of the newly-opened $11-million improvement project at south Columbia’s New Haven road, Lemone Industrial drive and the ramps.

939 the Eagle program director Peter Thiele has produced a video which highlights the U-turns that many motorists have been making. If you’re heading east on Grindstone and want to travel north on Highway 63 towards Home Depot, you need to be in the right lane. But many motorists are still making U-turns at the light. Peter reports crews from the Missouri Department of Transportation (MoDOT) have installed a new no-turn sign there.
