For the N99 traffic safety measures project, soil surveys must be carried out.
To achieve this, it is necessary to close the N99 in both directions for two nights between De Kooy and the roundabout towards Balgzandbrug.
The work will take place during the night of 9 to 10 September and from 10 to 11 September between 23:00 and 05:00.
If you wish to use this route at this time, the diversion route in both directions is via the N9, N248 and N249.
