Idiot planning of roadwork

Although it is already a few months lower nevertheless: in the morning giant stowage on the A66 of Mainz/Wiesbadennach Frankkfurt. In itself nothing unusual there, but the cause: mowing work! And in the evening exactly in the opposite direction. So the mowing work took place precisely in the direction of the journey, in which at the time the higher volume of traffic was to be expected, so that the traffic jam behind it was particularly bad. Had it not been more useful to pass the mowing work on the side In other words, in the morning, away from Frankfurt and in the evening, into Frankfurt?
