GroenLinks (although in the council of the province), Party for the Animals and the SP are opponents of doubling. Bad for nature, more nitrogen emissions, more nuisance, need not demonstrated. It has all come up in discussions in the Provincial Council in recent years.
The political opponents see more in a total overtaking ban, if necessary enforced with physical measures such as obstacles in the middle of the road or even a median with a crash barrier. And the speed of those parties may also be reduced to 80 kilometers per hour. Good for nature and the collision speed is lower in the event of an accident.
SP party chairman is happy with the scrapping of parts of the road that have been duplicated.
