The National Roads Administration has announced that the CR308, also known as "Martelerstrooss", on the CR308 will close from Monday 22 September 2025 at 8am until March 2026 between Grevels and Herheck.

According to the press release, the closure is due to works being carried out by the intercommunal syndicate for wastewater treatment (SIDEN) in the north of the country.

A diversion will be in place via Grosbous, and drivers are advised to allow extra time for their journeys while the roadworks are ongoing.
