I guess ramming your head into a brick wall/plain old obstreperousness sometimes DOES work.
The Iowa DOT is prepared to allow an intersection with future four-lane US 61 and a side road south of Wapello, the Muscatine Journal reported nearly two weeks ago. This is what (or reasonably close to what) Louisa County supervisors and local residents have been demanding.
The plan, according to the story, involves a “J-turn” intersection. A J-turn is similar to a Michigan Left, except that no traffic on the cross road is allowed to go straight through. They have to cross two lanes of traffic to get to the U-turn, then cross two lanes again.
The J-turn concept was floated and shot down at both the US 65/IA 330 intersection, now an interchange, and the US 30/US 218 intersection, soon to be an interchange. This would be the first J-turn location in the state.
