@hayify it was a problem for the first few days of the knip.
I am skeptical that it is still a problem.
Regardless, the knip is happening for 6 weeks. I have seen nothing to suggest that the traffic on the Kattenburgerstraat is at a "project-cancelling" level.
I believe that the right wing media and politicians are inflating this "problem" to push their own agenda.
The Kattenburgerstraat has never been a low-traffic street, which is why it was redesigned a few years ago already.
