In preparation for the realisation of the ring road and the high-water channel of Wanssum, ECG started investigating unexploded ordnance in February this year. In recent weeks, several grenades have been found.

The explosives were detonated in a controlled manner on 31 March and 13 April by the Explosives Clearing Service of the Ministry of Defence (EODD). Before the Gebiedsontwikkeling Ooijen-Wanssum can be implemented, the entire project area must be examined for possible explosives.
