Overview
- Rijkswaterstaat counted about twenty large potholes over a 5‑kilometre stretch of the A50 between Vaassen and Epe and closed a full lane for thorough repairs, with work continuing on Friday.
- Noord-Holland closed the N244 (Westdijk) in Alkmaar overnight from January 15 to 16 to fix frost damage, with traffic and bus line 123 rerouted.
- Noord-Holland scheduled overnight closures on the N201 at the Waterwolftunnel in Aalsmeer from January 19 to 20 to repair potholes and manage tunnel tube access.
- Crews are performing nightly temporary repairs across multiple routes, including the A1, A28 and A50 in the center and east, and the A7, A28 and N33 in Groningen.
- Open-graded asphalt (ZOAB) and road salt are intensifying deterioration by trapping water that expands when frozen and by weakening the bitumen binder.
