Overview
- Rijkswaterstaat closed a full lane on the A50 between Vaassen and Epe to repair roughly twenty large holes found over a 5‑kilometre stretch, with work continuing into Friday.
- The Province of Noord-Holland scheduled an overnight closure of the N244 at Westdijk in Alkmaar from Thursday 22:00 to Friday 05:00 for patching, with traffic detoured and bus line 123 rerouted.
- Damage is also reported on Groningen routes managed by Rijkswaterstaat, including the A7 and A28, with additional issues on the N33 and a previously repaired meters‑long defect on the A32 near Wolvega.
- Officials cite the vulnerability of ZOAB surfacing during freeze–thaw cycles, where trapped moisture expands into pores and dislodges stones, creating cracks and potholes.
- Road authorities are using rapid temporary patches and immediate full repairs where necessary, urging drivers to slow down and report major defects via national and provincial hotlines.
