Repairing roads is necessary in every country. Sometimes part of the road have to be closed to repair or work on the other side. Here, in Germany, they would have installed 2 temporary traffic lights to solve the problem. It’s amazing to see, who different some solutions for common problems are: taxi van + STOP/GO-sign in a workers hand. Btw. years ago, they would have ordered 2 workers with a flag to manage the problem here. But nowadays not without the temporary traffic lights.
